E) none of these

Question

Quizplus · Accepted Answer

Fructose 2,6-bisphosphate is not an intermediate in glycolysis or gluconeogenesis but plays a crucial role in regulating both processes, especially by activating phosphofructokinase and inhibiting fructose 1,6-bisphosphatase, thus promoting glycolysis and inhibiting gluconeogenesis.
