Quizplus · Accepted Answer

Pyruvate carboxylase is the anaplerotic reaction that converts pyruvate into oxaloacetate, which balances the input of oxaloacetate with acetyl-CoA in the citrate cycle. Malate dehydrogenase and malic enzyme are not anaplerotic reactions, and pyruvate kinase is not involved in the citrate cycle.
