Molecular and Cell Biology (Nursing)

informative and interesting way of conveying the subject which helps understanding them much easier.

Easy to understand.I like how she uses examples to illustrate passive vs. active transport.

Amazing lecture, Dr. Georgina lessons are by far the best I've had in citology. Very clear and straight forward, perfect for the Mcat. Thank you!

The most important part of this lecture in my opinion is the analogies that Dr. Georgina offers. It really help us to understand for example when she associated the Golgi Complex with a Fedex facility, or when she connects the fact that liver cells have more SER since one of its important functions is detoxification.

So clear and to the point - perfect - love this video

Very well explain and the quizes are a great help

Dr. Ahern is amazing at linking what he's about to teach to previous videos.

So far so good. The videos are easy to follow and I love the questions that pull up at the end of the videos to recall the information. Looking forward on finishing the rest of the modules in biochemistry, including all the other sections.

The video by Lecturio provides an excellent overview of the electron transport chain and chemiosmosis, two of the most important metabolic processes in the cell. These processes work together to produce ATP, the cell's energy currency. One of the most interesting things about the electron transport chain is that it is a highly efficient way to convert energy from food into ATP. The chain uses the energy from NADH and FADH2, two electron carriers that are produced during glycolysis and the Krebs cycle, to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is like a dam holding back a reservoir of energy. The ATP synthase enzyme then uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate. This process is called chemiosmosis. The video does a great job of explaining the complex steps of the electron transport chain and chemiosmosis in a clear and concise way. It also provides helpful animations and diagrams that illustrate the process.

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

she is doing very well in explaining the topics and precise.

The lectures are not bad, they have the material, tbey are very well spoken and easy to undersgand. I find some quizz questions to not be relevant, i believe i won't be aske dthese questions on exam. And sometime the material itself feels dry. I am more of a doers, so by solving more complicated questions with the help of a professor would my learning experience much better. But over all not a bad course.

Simple, not over-complicated and understandable, all great signs of an amazing lecture.

it's very easy and simply explained and I loved it It was very helpful

Great material easy to learn good pictures …..thank you so much

I am appreciative that Dr. Ahern took the time to update his lectures. Shows he cares. Thank you!

The information is presented in a way that is easy to understand! Thank you ????

very confused and not organized I feel like its too messy and i can't catch the points

Bio means life, chemistry means the composition of matter and energy requirements for life to exist. Chemicals and anyone

I am enjoying the lectures. I have two, very minor issues. 1. They are a bit too "granular". Some are so short as to prevent you from digesting the material as it is presented. 2. On several occasions, the questions were not covered in that segment but rather in the next!

It was just what I really needed I love lecturio so much

An excellent and detailed description of each phase with emphases on correct language.

All the lectures have been so, so helpful. Thank you so much!

Kevin is Amazing man, his body language get a lot to his explanation!

lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.

excellent explanation of topic very difficult to understand for a med student

Breaks concepts down easily and love the review questions. Helps solidify learning.

Thank you, Dt. Cornwall, for this chapter!!! It was very useful and finally, with the help of your tips, mnemonic and your awesome teaching style, I could understand the process!

very new insight to explain macronutrient and fruit for thought

Really liked Enough chemistry to explain it / not more Shows that she is passonate about the subject

There are mistakes in the video and they make the material more confusing than it should be.

Nice delivery but as much as Dr tries to break it down,it looks a bit abstract. Perhaps some mneumonic would help

I understood very well the topics. I learned things I didn't before in school

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.

I am a biochemistry student, the videos on lecturio have been so amazing. The lectures are superb. The language is easily understood and in a very friendly way. The concepts are been discussed fully and appropriately. It has made me to understand biochemistry more.

ok ok ok ok ok ok ok ok ok ok ok ok

Thank you so much It was great I enjoyed watching these videos

just got the structure formation of a f actin support epithelial

Very good teaching. Very good images and very good explanation.

I like how Dr. Kevin discussed all the topics, simple and easy to understand.

Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.

The lecture breaks it down so simple that it’s easier to understand. There’s still more factors that I’m sure they’ll be discussed in other lectures but it’s perfect to help to create a strong foundation in your knowledge

Great Visualization and the elaborative method of teaching is right according to my mind.

very clear , and natural. High yield, very in depth. Great knowledge gained

brief , clear, high yield, relaxed, in depth lectures. With a question and answer section at the end of every lecture. I'm loving it

FINALLY! I get replicated homologous chromosomes! Professor Cornwall cleared up a haze I had about this point for years in 3 seconds. I don't understand why there are not more people who emphasis the difference between homologous and replicated homologous chromosomes. Thank you Professor Cornwall.

Dr Kevin explains the concepts slowly and with emphasis. He also includes the physiological aspects, making biochemistry sound more biological rather than chemical

I loved this lecture ´cause dr ahern was so clear and it really helped me understand this topic.

The professor teaches very well, and difficult concepts are taught in a clear, concise manner.

Basics of this course can be explained in a very detailed manner

The lecture was simple understandable and Clear , it gives a broad explanation about the fundamentals of biochemistry

Made something so complex easy. I've always had trouble here.

The content of the lecture/presentation is excellent. Has somebody else prepared the material?

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

Excellent resource. Thank you. I also enjoy the quizzes and practice medical scenarios.

He explains on a perfect and short way making it easier to understand

Very informative and detailed. It allows you to understand the concepts on a fundamental level.

Excellent review of the basics; been a practicing Doctor of Chiropractic for 27 years and your videos are bringing it all back again! On the way to taking the MCAT to get my medical doctorate in Pediatric Neurology specializing in neurosurgery. Planning on beginning practice when I am around 68/69...my second career. Thank you for helping me do this great endeavor!!

Five-star score not only for the high-yield information but also for the excellent teachers, spaced repetition tests and articles. Thank you all for bringing this amazing learning format!!

Really good explanation. And I like the professor. I understood

Very good lecture! Interesting clinical correlation (celiac disease). Thank you!

Please is important to add more clinical correlation, clinical cases and bridge to other areas: pharmacology, microbiology, etc. Usmle test the integration of knowledge.

Interesting. Mental thirst quenchinly good. Interconnected. Just enough info. Dr.kevin fun lectures.

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

This course is an excellent presentation of biochemistry. Professor Ahern presents the material in a clear, concise, easy to understand format that is easy to follow. I really like that I can pick and choose the lectures I need to watch, particularly those that I need to prepare for my upcoming exam. I find the review questions very helpful. Overall, I am finding the course very helpful and I am looking forward to completing more of it.

Like the step-by-step discussion. Make it easier for me.

not very engaging with the viewer, and it could be even more dynamic

I love it! It's clear and concise! Dr.Ahern is a gem to learn from. He breaks it down to where I can understand.

Nice speaker and illustrations. The lectures were engaging. Thank you!

Kevin Ahern is a really good teacher, I really enjoy his lectures, but sometimes it's hard to follow the lecture due to the presentation picturing one thing and him talking about something else. And also when he's talking about about the presentation I wished he had some sort of pointer so I would be easier to know what structure he's talking about????????

I love her course. She explains in a very understandable way.

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

The presentation is very nice and helpfuly The organization of topics was very good

I am no longer scared of metabolic pathways. thank you so much.

I'm impressed with how high yield the information is. The professor touches very important aspects in just the shortest time that one video has, and that is really impressive. I do have a degree in Biochemistry and molecular biology and so this is really making me master the course gradually. For sure I'm recommending this course to my friends from same college already who aspire studying medicine like me.

The videos are shorts and specific an also great explanations

I liked these explanations, but if you are a college student this may not be for you

Great explanation with great examples . Knowledgeable in subject matter , content up to date

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

Thankyou so much for the opportunity to relearn most of the important and key concepts related to this cornerstone foundation to Medicine & Life Sciences! Wish I had this tool in my undergrad days!!

He is the best here , I swear Idk but I like him

Great course for introductory level biochemistry. Prof. Kevin Ahen is a great teacher, knowing not only the topic but it's historical background...

He's a legend ooh I don't know what else should I say to complete 10 words

biochemistry was tough as I havent chemistry before. Had to keep reviewing, loved the tests and course presentation and so satisfying when i got the answers right. Great system for people like me . cant wait to do other subjects when i finish this one.

what an amazing lecture god bless u sir and i wish to meet u someday

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

I understand very well, thank you Professor Kevin, these help me a lot

It was much needed review for me in general. Thank you.

Enjoyed these videos very much. They helped me understand concepts I was struggling with.

Great work here,,, I’m so happy for the clearly understandable English

Nice course very complete in every sense, I like it, keep like that.

Awesome overview! Thank you! Particularly liked the gluten example. Also graphics were good - will stick in my brain longer.

I dont know if its the diagram or what the doctor is saying but i just cant understand the MAP kinase and the GEF and everything else afterwards

I just find the need for an extra time revising this, particularly offline. I always find my self making some notes unlike Anatomy!

Explica las cosas super simples y puntuales, se memoriza rapido de esa manera

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

The video highlights the important concepts about the hydrophobic amino acids group

I recommend include the cc out of slides screen, the letters do not allow to watch the information

adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

Me encantan las clases son muy explicativas y muy detalladas , simplemente excelente!!!

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

Concise and clear; exactly what I needed for this topic, thank you.

Good amount of detail in digestable amounts. Very much appreciate able to run the videos at different speeds.

No explanation at all just reading , sorry for that , No interaction

It's great to learn from someone who's enthuisiastic about their specialty and even better at teaching it. Thank you Dr. Ahern (:

I like the short videos. They described what’s important and later you get questions about the video.

Me agrada como explica las cosas la Dra, creo que lo hace que sea entendible de forma sencilla para cualquiera

I love having access to such rich learning material, thanks for making this an available resource. My only criticism would be that the quiz questions could use improvement and the professor could talk slower to make note taking easier. Overall, very grateful to have found this!

It is a good explanation for a complex topic, with only the most important

complicated topic but I think I got it, though the Tyrosine kinase itself is a bit complex

I like the format - the lectures are "short and sweet". The lecturer is reasonable easy to listen to. Perhaps it is just because this is a foundation course, but it does feel this material may not be in-depth enough for USMLE step 1. (Or perhaps because it's re-used for non-USMLE students?). The questions are just "okay". There are a few errors, and a couple questions could be worded better. It also seems that some of these questions are testing material that seems only marginally important, and may not be very "high-yield". I wish there was an option to flag review questions to not be included in the "spaced repetition". The "spaced repetition" idea should be for memorizing the most important details, and I don't really want to be memorizing questions that I think are of little importance, incorrect, or poorly worded. (It'd also be a good way your you at Lecturio to decide which questions should be revised - if many people flag it as "don't review again", the question probably needs revision.)

Understandable!!! Easy to remember! And pretty useful!!! You really need to learn basics topics in Med career it surely make you to be highlighted over another students

It helped me clarify some topics I had been having trouble with.

Sorry, the following videos have the information that I was looking for, sorry again

the instructor is very clear and is easy to follow

Dr. Cornwall did a very great job with this.. The big picture simplified everything and made studying into little details easy.

el contenido esta muy bueno, solo que la traducción tiene falencias y dificulta entender los conceptos adecuadamente.

Everything is confusing. The diagrams and what she was saying didnt allign. ALso she never gave the answer to the number of chromosomes in each stage of meiosis and mitosis

I loved it, really interesting and easy to comprehend, thank you very much :)

Need more mcq 's for practice and good content. Very clear concept s

The lectures are great... But I just feel like they are too expansive... Not very suitable for a dedicated study period

Very good Thanks Really it doesn't take much time and its really good

the lecrure is detailed and very comprehensive it is well presented i also liked the quiz that comes afer the lecure.

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

Dear sir/madam In regard to the Biochemistry basics,I am much satisfied by the cours.In fact,the videos concerning biochemitry basics are well summarized and are full of useful information in the regard of médical studies.Because of this,I am enjoying the course and continuing either to learn much more . Yours sincerely Asher Hategekamungu

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

The video episodes are way too short, need to go back and start over every 3-4 minutes. I think there should be a option to view the topic in one full video. Otherwise the subjects are well covered in an understandable manner. Many thanks

The way of teaching of Georgina is really impresive, i understanded everything. The best classes ever.

The course was easy to follow and has good illustrations of the concepts. I also like the quiz portion of the course.

Very comprehensive lecture . It' s clear and simple. Thank you for your work .

Great professor and easy biochemistry topics to learn with good explanation.

I work in a large public hospital biochemistry routine department, when I studied this subject there where no computers, only text books. So this is a refresher and update of the subject. I am enjoying this 'new' way of learning and it enhances my work knowledge as understanding theory is important for performing work well.

Great lecture! Very simplified and friendly explained. Thanks so much !

I like his style and respect his effort. I've been using these lecturers to review my knowledge

Dr. Cornwall makes the topics easy to understand and retain. Her approach is not overwhelming but yet not so simple you are bored.

Very detailed. Moves through information and a good pace. Sifts out the important information versus stuff we don't need to know for the exam.

the concepts are clear and the time is enough, examples are short.

hi Biochemistry's videos are interesting and give me information, the orator pronounce correctly. As you know I do my best to prepare ecfmg exam and board examination next, of course after having sufficiently training and advices under your guidance I would like to apply ecfmg examination this year, now would you please give me more information for preparing step one and step 2 exam.

I believe the term is entropy is misused in this lecture.

Misuse of the words fludity and stability as if they were synonyms makes answering the question at the end confusing. Other than that, it's a good lecture.

Awesome analogy great lecture! Very nice lectures overall I really enjoyed them. even though I have taught this topics and I know them fairly well. I enjoy little gems of information I received through these lectures, and new understanding

I like how Dr. Cornwall recaps chemistry and relation to energy to cells. Her hand motions help with my learning and understanding. Thank you.

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

I like the practical comparisons used for better understanding and remembering the topic, makes it much easier and more entertaining!

Concise and to the point for basic understandment of the subject.

Talks clearly and explains all the key points so that you can understand the lecture in simple terms

Studying Biochemistry lectures helps me to understand and hold in memory every each case,,, so this is the best ever

It was a great lesson thanks for everyting short and briefly everyting.

It’s not a bad lecture but it’s bulky stuff that isn’t simplified to hold ones attention, don’t get me wrong, it has its highlights but it could be more interesting.

Great lectures, very clear and understandable! Thank you, Dr Georgiana Cornwall!

Great lecture which allowed me to understand the topic much better than I was taught

All the explanation are precise to the point...and covers all the important concepts

Explains concept very well with good analogies that further enhances my understanding.

Dr Cornwall has the gift for teaching!! She explains things very well, thank you!

The professor is excellent. I like how he explains things. Some of the professors move their arms around a lot which can be distracting or spend the whole time looking down at the computer. With others it feels like all the do is read from the slides. However the biochem lectures are very well done and by far my favourites so far.

The module is complete but the questions can get too easy

I really enjoyed the video and it made me learn, also I liked that are short videos

They are so awesomely explained and very helpful thank you. I’d love the videos to have that ten second rewind or fast forward arrows like YouTube does, and then it would be perfect.

Very concise. Great illustrations. Thank you. Thank you. Thank you

Thank you for your knowledge and for spreading it in this way for us, the students.

The lecturer makes the topic interesting, easy to understand. One begins to appreciate how these things link with everyday human existence and how they play a pivotal role.

Good, where are the rest of the organelles (like peroxisome)

Need lot of detailed explanations.. especially in videos. The teacher is really good but the script is lacking too much.

its good and thorough, also covers minor lipid types! good to learn

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

I love this app but can get a little confusing when the professor uses the wrong words or accidentally says the wrong thing. Do you not edit errors out? It’s a great platform just needs a few tweaks here and there.

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

This is pretty good introduction! haha how to control the cell cycle

just basic to litle details course.easy to understand it.

I think it is an entertaining way to learn the history of Biochemistry.

I love this guy. The way he explains makes Biochem look easier

He is clear, short, and simplify the most important points

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

I like so much the content of this course and how the doctor provide the information

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

Concise with good use of slides and professional presence and dress.

P53 GeneRate this lecture P53 Gene Rate this lecture P53 Gene P53 Gene P53 GeneRate this lecture

extremely helpful when the amino acids are divided in functional relevance.

Amazing lectures. Simplifies complex pathways and process. Really fantastic! Watched every lessons.

:) Thank you . everything in this lecture is clear. like it very much.

Almost no information really disappointing. Use Step 1 2018 page 46 ... Even a student could have presented the topic in more depth as it is important.

just excellent , the content and the preparations were realyy excellent and goes very easy.

I believe that she is a great lecturer but, the issue is the way of delivering the lesson and how much was she ready to record the tuition. anyway it was a good experience for both of us, she let me search a lot for the genetics to unwind condense informations :)

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

Very disorganised way of explaining concepts It would be much better if things were presented in more detail and if the presentations were structured adequately

it was described in a simple and easy way to understand, thank you.

This video did not really show Aspartic Acid or Glutamic Acid?

The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.

He very easily simplifies things. So this is why I give him a five star review

Amazing, loved it very much. Easy to follow and clear.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

I feel like she is just reading notes that she has been just handed over.

The presentation is simple, short and concise preparing students for more detailed content. I believe that this is an efficient approach toward a broader base of an audience. Thank you!

as a beginer i didnt couldn't understand anything the lecturer is talking about and the lecturer is way too fast

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

Dr. Cornwall is very thorough and paces herself very well in relating core concepts.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

So much more simple than my lectures. Thanks for the detailed lecture. You're a life saver.

Direct , and easy to follow. The length of the video also helps.

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

Easy to understand and the explanation are very clear. Thank you very much good job!

In my school we will take this lecture in 2 hours!!! Way too short and superficial

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

I found it really helpful. Your explanations were clear and easy to understand.

As much as your stories are interesting for the ETC gradient It does not fit my learning style. It would be nice to have clear scientific language about what's happening. I can't write a story on my exam paper. Perhaps this is just me.

Easy to understand and very complete. Thank you for your time, helped me a lot

Thank you for the video's theses are really helpful. look forward to keep learning.

Feels like she is not comfortable with information she is teaching. Accuracy of information (and spelling!) is sometimes questionable.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

Great Explanation !! I wish we would have had you as a teacher. :)

thanks for teaching me in such a clear, precise, and yet enriching way

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

It was very precise and up to the point. The presentation was interesting that triggers to study better .

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Great job, Dr. Ahern. Thank you for bettering my understanding of these concepts! Used as a supplement to lectures and powerpoints, your videos on Lecturio have been extremely helpful to me!

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

I am a biochemistry student studying in the UK I found this so useful especially as a foundation in my initial year of study.

I love the visuals, her method of speaking and the transcript at the end

You make it much more easier. However, I still understand all important points. Thank you!

Good lecture, but not USMLE focused. This is more of a general biology lecture than a USMLE prep lecture. It seems to me that Lecturio is not making the difference between MCAT prep and USMLE prep. The lectures look more like MCAT prep lectures and not USMLE.

I like the way she expresses, you can easily understand her

best prof in the world explains everything so good that even a kid will understand

Its a little bit dificult to understand but the information its complete and tables and graphics helps a lot

Really great explanations of the whole process. Was not happy that I had to relearn Krebs and ETC but actually found these videos enjoyable and valuable.

Great enzyme analogy! Enzyme is the friend who puts his two other friends in contact with each other so that they can start talking and dating ;)

Nothing on how p53 relates to RB or how p53 induces p21 to inhibit CDK thus acting as a tumor suppressor by not allowing cell cycle progression. This info is found in the the First Aid for the USMLE so it is probably important.

In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

his teaching is clear and it is not allowing me to get even a single doubt

i could understand the concepts better. explanation was good.the charts were self explanatory. it made me feel bio chem much more interesting.

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

This is not a USMLE 1 focused topic, an important material for the step, it's so superficial either the question that is a first order question. Need to going deep in the topics, we're not an undergraduate students.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

First of all I would like to say that I really appreciate all of the effort by the professors and Lecturio to do great lectures, however, I would like to say, as well, that you need to focus on the exam format (In this case - USMLE Step 1). For example, in this lecture it was asked: "Which of the following is NOT a lysosome related disorder?" that is pretty good, because it has a clinical context with the subject, however this " lysosome related disorder" have never been taught by Professor Cornwall.

Very clear what is going on. I understand it much better.

Loved the lectures, especially the lecture on the electron transport chain. Dr. Cornwall had a really useful analogy of the ETC and kids (electrons and hydrogens) going to the prom (ETC) that really made the concept stick. Very good job!

The chapter about cellular structure has given me clear explanation and enhance my knowledge about the different functions that the plasma membrane assure. The course just makes my understanding of cell dynamic very straightforward.

It's an excellente teacher! She uses easy analogies that you can memorize quickly and gives you a summary of your class (in my case). Greetings from México!

High yield facts and clear explanation, the fundamental elements and efficient route to master biochem!

I am new to this curriculum, however, I would like the lectures to be longer. I am hopeful that other lectures are much more detailed, e.g. gene regulation/expression. Lecturer is very knowledgeable, clearly.

I liked very much this course. It's very interesting and The good teachers.

very good, is complicated, but i understand everything, she is a good teacher

I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.

Gooood job LoL and really a good story-maker????Thank you very much! Amazing, very impressive!

Thank you very much!! So funny and interesting! I laughed many times LoL also learned A Loooot!!!

I do not think there can be any simpler explanation of these concepts. Dr. Cornwall takes her time to explain these concepts in a way that they stick with you, and the analogies she uses engrave them into the medulla so that you can relate to the concept. You can't beat this! This is exceptional!!!! Thank you so much!!

First step to refresh and understand different concepts. Highly recommended.

I like the fact that the lectures are detailed and Dr.Cornwall makes it fun and easy to understand.

This lecture was excellent in every way, I must say DR. Cornwall is a Pro in intermediate metabolism. I couldn't understand this processes better in medical school than she has made me.

Based on explaination. I felt there was some lack of informations. In some area needs to be more profound.

Great lecturer who is knowledgeable about the subject. However the animations in both mitosis and meiosis would have been in motion so the explanations were tuff to follow. overall good attempt. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

Excellent lectures, you can understand in a few minutes the basics of difficults topics

couldnt understand a thing. Please try to use animation to explain better

Classes have an excellent quality, however there are small mistakes when you´re reffering to some specific molecules such as cAMP and cGMP because in some ocasions, you tend to exchange one with the other in just a few ocassions. Nonetheless, the overall course is excellent, with clear explanations.

How I wish I had this when I first started medical school. The explanations were clear and concise. The use of simple words enable me to understand it well as well as the option to pause at anytime allows further internalization of the facts.

u r so good like honestly amazing thank you so much professor

I learned a lot about cell structure in the most simple and efficient way.

It is too much Helping. It is Awesome and helpful

The lecturer uses great analogies to make concepts easier to understand.

Very good explanation of concepts. Animation could be added for excellent explanation.

Every topic was clearly explained and I could understand them very well.

The lecture was very intriguing! Dr. Ahern is so well articulated!

I don't waste my time going to any biochemistry lectures at my medical school because I know that Dr Cornwall explains all of the content more clearly, in more depth, in less time. I always finish her lectures excited for the next one!

Brilliant! I have always found these topics extremely confusing at medical school, but Dr Cornwall is able to explain them in such a way that they seem straight forward and easy. This certainly replaces lectures for me! If anybody is unsure about trying this course, they should definitely try it! Dr Cornwall is the best biochemistry lecturer I have seen!

A great lecture. I am a high school student and i struggle with biology. I get a better explanation from your lectures and I am not even a native English speaker. Thank you so much!

the lecture is good it educates on how bichemistry is related to other fields in life

I think this course is really informative, though I would like some more details in subjects like RTKs and G coupled proteins. And also please add English subtitles to this course! I'm not native and I found it hard to keep up!

The courses are very concisely presented, it is really useful for preping for an exam

Need more details Need to go slower But overall not bad

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

Needs more substance. This was barely long enough to be an introduction.

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

Good clear concept review. Could use more specifics regarding cyclin and cdks.

Everything was on point .. Will definitely share with my friends.

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

I found the lectures to be very informative and composed of high-yield information for a relatively quick review of the subject. The only reason I give 4* is because of the few technical problems with the course; but, in regard to the course material, Lecturio provides a wonderful review of Biochemistry with Dr. Ahern.

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

I like the teaching style and material presented! It is clear and understandable. Thank you!

It's very clearly explained and very useful for my studies. I would like it to be a bit more detailed but not too difficult.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

i like this lecture. way of representing and explaining is quiet good.

Very nice but there's some need of detailed explanation and then it would be perfect

Awesome job, I wish you were my teacher at my university! So clear!

What I loved the most about this lecture was how Dr. Cornwall actually took her time to explain the concepts discussed, and even used simple analogies to ensure that the information was easier to digest. This is something you find lacking in many professional lectures. Thanks again Dr. Cornwall!

very good course, i wish i have money to pay the all course

Thank you dr. Georgina Cornwall! Everything was perfectly understood with your lecture!

She spends half an hour explaining the steps of meiosis and doesn't even get into details... I'm not sure how she can manage to explain such simple topics in such a long time (it's half a movie time, for God's sake!). She should base her lectures on Molecular Biology of the Cell, by Bruce Alberts et al., AT A MINIMUM. Lecturio has many excelling lecturers; unfortunately, Dr. Cornwall is not one of them.

These lectures are made simple for someone like me who is very vulnerable to biochemistry.

As it's my first lecture, I think I have to work a lot for getting great benefits from your great tutors. hence I had to give this rate. right now there are no such dislikes. well, thanks a lot for the kind assistance.

Great lecturers and thorough explanations for every subject. After watching the lectures, I actually understood and retained because his lectures are extremely well organized.

This is quite helpful. I am a pre-Medical student and I'm fully satisfied by the leacture. I'm able to cover all the syllabus. It's helping me to save time. I dont need all those notes n stuffs. Most important i can practise lots of questions! I'll recommend all Medical students to take this amazing leacture for once so that you'll be able to understand. Thankyou @lecturio! ????

A ERY INTERESTING COURSE ,BUT REQIURES A LLOT OF STUDY TIME TO UNDERSTAND THE AMINO ACID CHEMISTRY. TO BE HONEST, I AM A RETIRED 85 YR OLD PHARMACIST TREYING TOEEP UP.

I really like the pace and clarity of this lecturer in how he presents the material. It would be nice to have animated pictures in signaling and transport. I also wish there were sections covering enzymatic catalysis & kinetics. Over all, very good! Thank you for making these

She is very detailed but yet not overwhelming with the lecture. It's been great help on my bio knowledge.

Not very hard to understand, sometimes a bit too "shallow". However most often very good. Even great.

I rate this five stars because I like to go over it while I do other things and more than once.

The overview of biochemistry is really helpful! The images are great, and the lecture is really high quality.

I was hoping for a little more details about the chemical makeup of the topic, however, I like how the entire video is layed out and described.

The Dr Georgina did it very well she know detail about the subject matter andinet did not express about her and execelentroll model for me!

I like the way the instructor presents the material , and the examples she uses.

Well, I love the way Dr. G explains, however, the lecture on cell control wasn't the best and needed more explanations and needed to be more simplified . I put five stars because Dr. G has helped me a lot and made Biology a fun course.

This course really helped me understand the cellular structure, I learnt more from one of the 20 minute lectures, than I did in a 3 hour lecture at university, so these really help!

Good and clear explanation, Dr. G makes it fun to learn biology.

Watching these videos from Lecturio is very much like being in my school. The difference is Lecturio is more fun and it encourages us every time we want.

With this introductory course, you will be exposed to the basic aspects of Biochemistry. Professor Ahern emphasizes that an in-depth knowledge of basic biochemistry will aid you tremendously in understanding life processes on a macroscopic level. This one course alone was well worth the one month payment of 24$. Every other course on top of that was an attractive but inessential addition..."icing on the cake"!

Professor Ahern is truly excellent! Amazing choice. He clearly explains concepts and shows sincere enthusiasm for the topics. You need to bring him back for lectures on amino acids and the urea cycle as well as the electron transport chain.

Very easy to follow, good flow and simply explained, exceptional professor! just wish the questions had explanations then I would give the videos a higher score .

it has helped me build my understanding of biochemistry. looking forward to more lectures

Love this course and Professor Ahern's enthusiasm keeps my attention. Being able to watch the videos over and over helps the lessons sink in. For the first time I'm enjoying biochemistry. Thank you for making these videos so affordable and easy to use.

Since is starting this biochemistry, it's help me to remember some of the basic concepts that I have forgotten

This is an amazing course! Prof Kevin has made every single details simple and clear. His deep knowledge and understanding of this subject is well reflected in his teaching style. The materials he used, are very attractive which makes it easy to memorize. I would definetly recommend this for both under and postgradustes students.

This course is well done. It's thorough. I'm reviewing things I've learned, and also moving on to more advanced material very soon. I wish I would have had this during undergrad.

The biochemiThe biochemistry is one of the best because the professor Ahern is a terrific docent who makes one love the lectures
