Which enzyme in the citrate cycle produces NADH?
A) aconitase
B) citrate synthase
C) isocitrate dehydrogenase
D) fumarase

Question

Quizplus · Accepted Answer

Isocitrate dehydrogenase is the enzyme in the citrate cycle that produces NADH. It catalyzes the conversion of isocitrate to alpha-ketoglutarate, with the production of NADH and CO2. Aconitase catalyzes the conversion of citrate to isocitrate, citrate synthase catalyzes the formation of citrate from oxaloacetate and acetyl-CoA, and fumarase catalyzes the conversion of fumarate to malate in the citrate cycle, but none of them produce NADH.
