Question

Quizplus · Accepted Answer

Pyruvate carboxylase is required to convert pyruvate to oxaloacetate, which is then converted to phosphoenolpyruvate by phosphoenolpyruvate carboxykinase. This is the first step in the gluconeogenesis pathway. The other answer choices are either not involved in gluconeogenesis or lead to the production of pyruvate, which is the opposite of what is needed in this pathway.
