- Which of these is associated with production of ATP during glycolysis? (Select all that apply) a) Conversion of 1,3-BPG to 3PG b) Conversion of 1,3-BPG to 2,3-BPG c) Conversion of PEP to pyruvate d) Conversion of 2,3-BPG to 2PG e) Phosphorylation of glucoseThe formation of acetyl CoA... A) occurs in the mitochondrial matrix, after moving across the outer and inner mitochondrial membrane. B) occurs in the cytoplasm prior to transport into the mitochondrial matrix. C) involves activation of acyl groups derived from pyruvate. D) A and C E) B and CDuring the metabolism of glucose in anaerobic cells, the enzyme lactate dehydrogenase is essential to allow glycolysis to continue. This enzyme catalyzes the reduction of pyruvate to lactate. Why is this so essential? OA) It lowers the pH. B) It re-oxidizes NADH to NAD+. C) Lactate stimulates hexokinase activity. D) Pyruvate inhibits pyruvate kinase.

Explain in detail. b) Due to the fact that glucose 6-phosphate is also an intermediate for the glycolysis pathway, the regulation of glycolysis and pentose phosphate pathway is very important. NADPH plays a crucial role in partitioning of glucose 6-phosphate between glycolysis and the pentose phosphate pathway. Explain this role of NADPH in detail.
- Listed are some hypothetical medical conditions, describe their effect on cellular respiration (specifically refer to the effect they will have on energy production). a) A person is unable to take glucose into their cells. b) A mutation occurs in the ATP synthase protein and it is inactive. c) The mitochondrial inner membrane is very permeable to H+.the reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generatedThe enzyme Phosphofructokinase (PFK) is a key regulator of glycolysis. A) Does ATP bind the PFK allosteric siteor the active site? B) Does high amount of ATP in the cell activate or inhibit PFK? Why? C)What do you suppose happens to glucose if glycolysis is inhibited in the cell?
