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.
