The image below shows part of a key catabolic pathway. If an individual had a deficiency for the enzyme required at point "X", would they still be able to produce a high rate of ATP during very strenuous exercise? ATP in Glucose Prep. phase Payoff phase - Pyruvate →→→ Anaerobic fate of pyruvate ATP out Select one: O a. No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD* to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis. Report question issue .Notes
