Each of the following catalyzed reactions of the citric acid cycle appears to be regulated except
A)citrate synthase.
B)fumarase.
C)isocitrate dehydrogenase.
D)a-ketoglutarate dehydrogenase complex.

Question

Quizplus · Accepted Answer

Fumarase is not regulated in the citric acid cycle, as it is a simple hydrolysis reaction that does not require a cofactor or regulatory molecule. In contrast, citrate synthase, isocitrate dehydrogenase, and a-ketoglutarate dehydrogenase complex are all regulated by feedback inhibition and/or allosteric regulation.
