A high NADH to NAD⁺ ratio would inhibit which enzyme in the citrate cycle? A) succinate dehydrogenase B) succinyl-CoA synthetase C) aconitase D) isocitrate dehydrogenase

Question

Quizplus · Accepted Answer

A high NADH to NAD+ ratio inhibits isocitrate dehydrogenase, which is the enzyme responsible for the conversion of isocitrate to alpha-ketoglutarate in the citric acid cycle. This means that if the ratio of NADH to NAD+ is high, isocitrate dehydrogenase is less active, which slows down the citric acid cycle.
