Principles of Bioenergetics and Fuel Molecule Metabolism

Principles of Bioenergetics and Fuel Molecule Metabolism

by Kevin Ahern, PhD, Georgina Cornwall, PhD

This course covers the material of content category 1D of the official MCAT exam content outline.

Bioenergetics refers to the study of energy transformation within living systems. Required for the most basic of cellular functions, biological systems have the ability to store and utilize energy in the form of nucleoside triphosphate compounds (e.g., ATP and GTP). Energy can be extracted from the intake of energy-rich foods and/or via cellular respiration, as in the case of anaerobic organisms.

In this course, the student will be introduced to the types of biological fuel molecules and other principles of bioenergetics. For optimal comprehension, the student should be familiar with the basic concepts of college-grade biology, chemistry, and physics.

Excellent help for Medical Biochemistryl course
By Anna M. on 27. January 2023 for Carbohydrate Metabolism

Clear and understandable concept with actual molecules shown aswell which is very helpful.

teaching method is boring and not helpful for my mind to understand
By Enarah R. on 04. December 2022 for Pathway Overview and Reactions – Part 1

not explned wel as the topic is difficult and you made it a lot much boring

My rating of Carbohydrate metabolism
By Johnson O. on 17. July 2022 for Carbohydrate Metabolism

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Thank you

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.
