Which vitamin is required by the enzyme that converts pyruvate to oxaloacetate, a key step in gluconeogenesis?

Question

Quizplus · Accepted Answer

The conversion of pyruvate to oxaloacetate is catalyzed by the enzyme pyruvate carboxylase, and biotin is a required cofactor for this enzymatic reaction. Therefore, biotin is the correct choice. Thiamin is not required for this reaction. Niacin is not a cofactor for any enzymatic reaction in the process of gluconeogenesis. Vitamin B₁₂ is not required for this reaction.
