ATP synthase is a protein that catalyzes the formation of the energy storage molecule adenosine triphosphate using adenosine diphosphate and inorganic phosphate. Which of the following are true for the protein, ATP synthase? Select all apply A mutation of Asp61 to glutamic acid would have less of a deleterious effect on its ability to synthesize ATP than a mutation of Asp61 to alanine A mutation of Asp61 to alanine would have less of a deleterious effect on its ability to synthesize ATP than a mutation of Asp61 to glutamic acid The F1 subunit is primarily responsible for translocating H+ ions across the inner mitochondrial membrane during ATP synthesis The FO subunit is primarily responsible for translocating H+ ions across the inner mitochondrial membrane during ATP synthesis
The enzymatic activity of PFK1 is generally measured by set- ting up a coupled enzyme assay system whereby aldolase, triose phos- phate isomerase, and glycerol-3-phosphate dehydrogenase are added to the assay mixture. For the latter enzyme, NADH is added and its change in concentration is readily monitored at 340 nm. Write the chain of reactions catalyzed by these enzymes using structural formulas, label substrates and products, and explain why the coupled en- zyme assay system leads to oxidation of NADH. While the chain of reac- tions is similar to those in glycolysis, there is a critical difference because of the dehydrogenase enzyme. Describe how this enzyme causes the chain of reactions to differ from those in glycolysis.
Please describe four different modes of the regulation of the pentose phosphate pathway.
Why is de novo biosynthesis of purines markedly elevated in patients with a deficiency in hypoxanthine-guanine phosphoribosyl transferase (HGPRT)? 5-Fluoruracil is converted to methotrexate by a DPD deficiency, leading to increased purine biosynthesis. HGPRT deficiency prevents purine salvage, leading to increased purine biosynthesis to make up for it. HGPRT increases pyrimidine salvage and thereby increases purine biosynthesis as a result. Increased purine biosynthesis is the result of ATP hydrolysis during the production of cyclic AMP.
