There is reciprocal regulation of glycolytic and gluconeogenic reactions interconverting fructose-6-phosphate and fructose-1,6-bisphosphate. Which one of the following statements about this regulation is not correct?

A) Fructose-2,6-bisphosphate activates phosphofructokinase-1.

B) Fructose-2,6-bisphosphate inhibits fructose-1,6-bisphosphatase.

C) The fructose-1,6-bisphosphatase reaction is exergonic.

D) The phosphofructokinase-1 reaction is endergonic.

E) This regulation allows control of the direction of net metabolite flow through the pathway.
