    • Proteins & Catabolism of Fats / Metabolic Regulation
    • Macromolecule Building Blocks
    • Catabolism of Fats
    • Metabolic Pathways
    • Control the Process of Metabolism

    Included Quiz Questions

    1. Acetyl-CoA
    2. Electron transport chain components
    3. Krebs cycle intermediates
    4. Pyruvate
    1. They must be deaminated
    2. They must be dehydrogenated
    3. They must be decarboxylated
    1. Pyruvate, Acetyl CoA, and Krebs cycle intermediates
    2. Pyruvate and acetyl-CoA
    3. Pyruvate and Krebs cycle intermediates
    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.
