Quizplus · Accepted Answer

Pyruvate carboxylase or phosphoenolpyruvate carboxylase are both enzymes that are involved in the conversion of pyruvate into oxaloacetate, a key intermediate in the citric acid cycle. This process is important for the synthesis of glucose as well as for the generation of energy in the form of ATP. However, the direct synthesis of glucose from pyruvate requires other enzymes and pathways, such as gluconeogenesis. The synthesis of amino acids and acetyl-CoA also involve different enzymes and pathways than pyruvate carboxylase or phosphoenolpyruvate carboxylase. Therefore, the best choice is C, to synthesize oxaloacetate.
