    About the Lecture

    The lecture Process of Metabolism by Georgina Cornwall, PhD is from the course Energy, Enzymes and Metabolism.


    Included Quiz Questions

    1. If ATP levels are high, it is important to directly inhibit the reaction that commits the substrate to glycolysis to allow the substrate to be available for other reactions, since the cell has ample energy.
    2. If ATP levels are high, this provides a mechanism to directly inhibit the Krebs cycle, thus preventing further generation of NADH, FADH2 and ATP molecules that are not needed.
    3. If ATP levels are high, it is important to inhibit ATP synthase, and phosphofructokinase directly inhibits ATP synthase.
    4. If ATP levels are high, this provides a mechanism to directly inhibit the electron transport chain, thus preventing the formation of a proton gradient in the intermembrane space of mitochondria.
    1. …negative feedback mechanism.
    2. …positive feedback mechanism.
    3. …substrate concentration.
    4. …the presence of O2.
    5. …the presence of CO2.

    Great!

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

     
    The Very Best So Far!!!!
    By Angela N. on 20. March 2018 for Process of Metabolism

    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!!

     
    Exceptional lecturer.
    By Anthony F. on 13. July 2017 for Process of Metabolism

    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!
