Energy, Enzymes and Metabolism

by Georgina Cornwall, PhD

Get ready for your medical exams!

The USMLE Step 1 will test your fundamental knowledge of a variety of scientific concepts, including energy, enzymes and metabolism, which is why it is essential to expand your knowledge of Biology. Who better to review these concepts with than an expert? Dr. Georgina Cornwall is a Professor of Biology at Colorado Mountain College. Dr. Cornwall excels at helping individuals learn and review the key concepts of Biology. 

Have direct access to self-paced lectures led by Dr. Cornwall and test your knowledge through high-yield, interactive quizzes.

This course will cover all of the following essential concepts:

  • Laws of Thermodynamics
  • Chemical, Endergonic and Exergonic Reactions
  • Bicarbonate Buffering System
  • Biochemical Pathways
  • Redox Reactions
  • Glycolysis
  • Recycling of NADH
  • Pyruvate Oxidation
  • Krebs Cycle
  • ATP Synthase
  • Cell Respiration
  • Metabolic Pathways

A deep understanding of Biology is necessary to do well on the USMLE Step 1. Without this strong fundamental base, moving forward in your medical career will be very challenging. So don't delay, start reviewing with an expert today.

Nice comparisons make it easier to learn and understand
By Tereza P. on 05. December 2019 for Chemical, Endergonic and Exergonic Reactions

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

By Rafael O. on 25. February 2019 for Energy, Enzymes and Metabolism

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

Not for me
By Natasha O. on 25. September 2018 for Electrochemical Gradient

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.

Excellent explanation
By Maria A. on 22. September 2018 for ATP Synthase

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