Which enzyme does not catalyze a reaction that releases carbon dioxide?
A)α-ketoglutarate dehydrogenase complex.
B)Pyruvate dehydrogenase.
C)Malate dehydrogenase.
D)Isocitrate dehydrogenase.

Question

Quizplus · Accepted Answer

Malate dehydrogenase catalyzes the conversion of malate to oxaloacetate in the citric acid cycle. This reaction does not involve the release of carbon dioxide. In contrast, the other enzymes mentioned in the question (α-ketoglutarate dehydrogenase complex, pyruvate dehydrogenase, and isocitrate dehydrogenase) all catalyze reactions that release carbon dioxide as a byproduct.
