Day 1: Biochemistry – Watch Videos

Hi, good day to everyone. I really wanted to make a review for this lecture, because for me it was a great brief and concise explanation. Thank you very much for the easygoing explanation Dr. Cornwall. I have a bachelor in cellular and molecular biochemistry from a US college and never seen anybody explain and organize all this material in a best possible simple way. English is my second language, and I had to study this topic both in English and in my original language, in collage, so I could be able to fully understand how they worked. This type of receptors and cascades involved, are a challenge to explain how they work in a very simple way; while you either try to understand by readding it on a textbook or see it on a picture, Dr. Cornwall does a really good job on how overall it works. To all my fellows studying this lecture, I just wanted to encorage you to remember that she is mainly explaining the overall function of the receptors, the enzymes and proteins involved, don't jump just yet to understanding all the types of pathways that go through the cascade. A quick tip for everyone to understand better this topic with this video: you could try to use both video and script at the same time, pause or rewind if you didn't capture what Dr Cornwall said, and re-read the script, review the slides with the images and write as you understand, that will make engage your brain and fully understand the topic as you go. Thank you again for your explanation Dr. Cornwall; thank you very much everyone for reading me and have a good study session. You all got this!

I am really satisfied with this service. It really looks like they've been putting in the hours and work to deliver this service.

Perfectly clear...not sure what the other reviewer is on about.

After watching her lectures on molecular and cellular biology, I had a wider view of these subjects. Well integrated, well explained, excelent service!

The pictures really help to understand these processes. Material about physics is usually boring for me but this time is was not so

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.

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

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

Simply explained. Can't emphasize more how important this is

I like the immediate quiz and 'notes' format after each video.

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

A great summary and introduction to an important but sometimes confusing topic. The questions following the mini lectures sometimes seemed out of sink, covered in a later lecture, etc. For students using this as a key resource, it is essential they understand that using the suggested textbooks and answering all the questions is necessary if preparing of licensing exams, etc.

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!

As a retired physician, still professing clinical subjects at a medical school, it is great to have an opportunity to revisit topics last studied in depth in the 1970s! It is presented in clear and digestible aliquots and in a logical sequence by qualified lecturers.

The teaching is basic and does not represent material tested on USMLE exams. The concepts are taught by an instructor unfamiliar with the actual exam. Technically, questions pop up in the middle of a sentence and sometimes before the subject matter tested was mentioned.

Concise and easy to understand content. Thank you Dr.Georgina!

Great review for practicing physicians who have been out of med school for some time.

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!

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

A very concise content with relevant short videos and quizzes. Great program

I love cell biology and this classes are amazing. Thank you

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

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

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

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

I appreciate these refresher and very well-explained building lectures.

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

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

Covered a vast portion of the basics that are the most important part of the foundation. The structure of the course is phenomenal and the way it is carried out is engaging and made extremely interesting. Concepts are crystal clear after going through the whole course. Thank you so much, psyched to have found this! I only wish this material was downloadable for future reference. Hoping it could be. Thanks again! This has cleared the slightest doubts Ive ever had, hoping to have many more courses conducted by Georgina Cornwall.

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

I liked to much because maintain the point of what are she explaining the theme with clarity and didactic form about the macromolecules of life the first principle to begin the content of the nature of the Body , systems organs ,tissues and cells.

Incredible Easy to follow the class The professor had my attention all the class

Nice explanation, very useful, easy to follow. very useful reminder of basics.

I could not understand it good at that in my university college friends

one of the best teacher ..yo mam ............really enjoyed it

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

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

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

I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(

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

lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.

I am in my first semester of Bachelor of Science in Biomedicine in Switzerland and the courses are helping me a lot. I can watch your videos after a whole day of studying and I am always having fun! I get a great overview and know what the most important concepts are. I also have no issues remembering what I learn here. Thanks a lot! I learn new things while answering the quiz questions as well, they are smartly structured and help a lot as well.

Love your lectures, Professor. It is helping me a lot reviewing Biology as It's been years since my basic science years.

Although the whole course (and actually the whole of Lecturio) is absolutely wonderful, I enjoyed this lecture with Dr. Cornwall so thoroughly, that it felt like time was passing by rapidly! Before I knew it, the lecture was over and I had learned so much! Dr. Cornwall has a way of explaining things that makes you understand is the matter longterm and makes you curious to look deeper into it. Thank you very much for everything! Eileen Dara Greetings from Belgium

I select leturio because its teaching method is very awesome knowledge base Usmle type based

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

La Dra explica muy bien y de manera sencilla, algo que me gustó mucho son las analogías que utiliza para dejar claras las cosas, creo que eso lo facilita

I belive she is very clear and resume complicated topics nicely.

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

not clear voice . . . . . . . . . . comparatively worse than other videos, others are good.

Very well taught, good refresher. The high yield points are in there too.

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

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

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

O really like it , because the lectures are very clear. And I understand everyrhing.

difficult subjects are explained by simple words by Georgina. Thanks so much!

I recommend everyone to Follow the 100 Day Study Plan given in Lecturio App. Its Amazing.

hi first of all she is talking very will as good speaker and the explanation in different lecture was so systematic and will prepared and hit the main points that I'm really interested to her course of biology.

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.

Most of us studying at this point (USMLE Prep) know this stuff well, however; this does provide a good refresher to get the juices flowing in the right direction while studying for the boards.

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.

Thank you dear Ms Cornwall l easily grabbed basic elements and mechanism of cell biology with your videos Best wishes

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

I really liked the videos they very clear and easy to understand , they best part is they are short and precise to the point .

The marcomolecules lectures are very good with excellent explainations of content

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

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

The knowledge is systematic, but I wait for long time to get a answer to my questions. And I still get no feedback.

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

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

Concise, easy to follow, great drawings, post questions provide a good summary of key points before

amazing lecture, finally i understood the tertiary structure for the first time

Good and informative, no bad comments. Good lectures and lecturer

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

Easy to understand and fun! Really useful! Great examples are provided!

I loved the correlation with margarine and butter, it helps to understand and remember the topic.

I found this lecture very concise and easy to despite being quite basic. I have always struggled with understanding atomic structure and feel that it's due to information overload. This lecture provides just the right amount of information to build on.

I liked it very much because it helped me access materiel that I already new without further complications. It was very easy to comprehend and I will recommend this to everybody needing this for whatever the reasons you need it for.

Appreciate too much, because after many readings in the books, finally I understand clear having the big picture of this topics . Congratulations to the Teacher .

she explains it to the point and doesnt waste time going around the topic.

Made it very easy to understand. Thank you very much!

a tough subject, but Dr. Georgina made it very easy and palatable, thanks soo much.

I just want to admit that this tuition is a hard one and she made it very easy.

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

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

Concise and clear beginning in cell biology and homeostasis to warm up.

I wish all professors prepared students for Biology courses with this explanation. Thank you for addressing this concept!

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!

the course was good, the first video was condensed with a ton of information and I think you should maybe think about splitting this kind of videos in the future, I was finding myself watching other youtube videos to study this subject. it is always good to use plenty of different source of information to develop a wide perspective on a subject. but in this case, I want to rely on lecturio only.

most of the things i catch from animation while only little from lecture (for which i had to pause the video to read all those stuff written there, which is time consuming). mam's speech seems quite a kind of nervous, suffocating type

5 rating is what you deserve , i really liked the way you illustrate those key aspects

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

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

Wow! Muchas gracias por todo el contenido muy bien explicado! Realmente fue muy interesante y, de gran aprendizaje asistir a todos los videos del curso "Introduction to Cell Biology".

great lecture, very simple and clear. I've finally understood bonds!)) thank you!

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

The combo of visual and review aided in maintaining info

This lecture and the one before were very confusing. You need to explain that the third energy level can technically hold UP TO 18 electrons (s,p,d sublevels) but it also fills up with the first 8 it receives. valence shells (energy shells) and energy LEVELS need to be better distinguished and not used interchangeably. Luckily, I knew the material and was able to straighten things out for myself using Google. How can I know that Lecturio will not have faulty lectures in the biochem module (material I'm not familiar with)? I am still within 10 days and am considering cancelling my lecturio subscription over this lost credibility in my mind.

It is very clear to understand. Great job Dr. Cornwall.

Prof Cornwall does a great job at presenting the material, catching my attention easily into the depth of the material while being precise with the content. Very easy to learn from :)

She talks so clear, understandable.. just a little fast but i havent got bored.. Thank you..

I love it so much!!! It’s been a truly rewarding experience for me!

Very good use of examples connecting to every day life.

VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT

I like the smooth flow of the subjects in this course and how they focus on small details that make you digest and understand the living human from very small details.

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!

There is possibly a mistake in galactosa geometric formula in the lecture

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.

She broke it down to the very basic and helped me get a good foundation

The explanation is very clear, I'm early to continue watching more videos.

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.

The explanations and images are well coordinated, making the review more interesting

The explanations and examples were clear and right to the point

informative. good review for this basic area as it has clinical correlations

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.

Excellent structure and content. Essential basics for chem and biol.Thank you.

Well organized backed with excellent methods of teaching & illustration. In summary, I found what I want in short period of time.

Me gusto mucho porque pude repasar el tema sobre la homeostasis.

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

I wish all the other professors had her didactics. Pointing clearly the goals of the presentation before and after the lecture helps us to mentally organize the subject.

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.

I read the curriculum and it looks good and flexible schedule to be prepare for exam.

The course is informative and up-to-date, which is really important for me. I took my science courses before 2010; now, I’m preparing to take the MCAT. It is an excellent review of content.

I really loved it, because PhD Cornwall made it really easy to understand.

Brilliant. I recommend this course strongly if you want to understand this topic.

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

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

This instructor makes this course enjoyable, and very easy to understand the materials presented here. I have already informed all my friends who are interested about going to medical schools about lecturio. Lecturio is a blessing to mankind.

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

Well explained she took her time tho but she did it well

An excellent, brief and up to date piece of information, ideal for quick recall

Well done by the professor with full of transfer sense.

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.

The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!

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 lecture were short and concise and were just thesame as what I needed to learn.

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

Thank you so much for beautifully explaining every single basic detail in chemistry. The modules covered up the required topics from the scratch to strengthen my basics.

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!

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

It helps very much. Thank You. I will share with my friends.

Very good keeps on track with my textbook. Taking Intro Bio

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.

Great breakdown of these biologically important macromolecules. Amazing detail on presenting each macromolecule and distinguishing polymers, monomers and non polymers.

The professor was very knowledgeable and presented the information in a clear and concise manner

Very good explanation and notes and diagrams. Dr has good quality teaching .

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

The lecture covered everything I needed to know for my upcoming test. I feel so much more prepared now!

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.
