__________ activates __________, thereby inhibiting pyruvate dehydrogenase. A)NADH; pyruvate dehydrogenase phosphatase B)Ca²⁺; pyruvate dehydrogenase phosphatase C)NAD⁺; pyruvate dehydrogenase kinase D)ATP; pyruvate dehydrogenase kinase E)pyruvate; pyruvate dehydrogenase kinase

Question

Quizplus · Accepted Answer

ATP activates pyruvate dehydrogenase kinase, which then phosphorylates and inhibits pyruvate dehydrogenase. NADH is a product of the pyruvate dehydrogenase reaction and can inhibit pyruvate dehydrogenase phosphatase, but it does not directly activate pyruvate dehydrogenase kinase. Choices A, B, and E are not valid options as they contain nonsensical characters or are not relevant to the pathway.
