Phosphofructokinase-1 is the main flux controlling enzyme for glycolysis. It is inhibited by high [ATP]. There exist metabolic circumstances in which the inhibition by ATP is overridden. Draw velocity vs. [S] graphs showing the inhibition of PFK-1 activity by ATP and the circumstance in which the inhibition by ATP is overridden.

Sonicating a suspension of mitochondria produces submitochondrial particles derived from the innermitochondrial membrane. These membranous vesicles seal inside out, so that the intermembrane space of themitochondria becomes the lumen of the submitochondrial particle. Explain (or diagram) the process of electrontransfer and oxidative phosphorylation in these particles. Assuming all the substrates for oxidativephosphorylation are present in excess, does ATP synthesis increase or decrease with an increase in the pH ofthe fluid in which the submitochondrial particles are suspended? Why?
Which statement is FALSE concerning glycolysis? Group of answer choices It is activated by high [AMP]. It results in a net synthesis of ATP. It results in the synthesis of NAD+. None of the 11 intermediates in the glycolytic pathway are phosphorylated.
Although phosphoesters are generally not energetic enough to donate the phosphate to make a high energy bond (e.g., a phosphoanhydride), the phosphate in PEP is used to convert ADP to ATP in the pyruvate kinase reaction. Carefully explain the ‘quirk’ of this reaction that makes it energetically feasible.
