Quizplus · Accepted Answer

Carboxylation of pyruvate requires biotin, which serves as a co-factor for the enzyme pyruvate carboxylase.

Answer: I 
 Pyruvate carboxylation occurs primarily in the liver, where it is used in the process of gluconeogenesis to produce glucose.

Answer: D and H 
 Glucose-6-phosphatase and glycogenolysis are involved in the release of glucose from glycogen stores and are not directly involved in carboxylation of pyruvate.

Thus, the correct answers are F and I.
