5. 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? FGP A) Fructose-2,6-bisphosphate Fructose-2,6-bisphosphate activates phosphofructokinase-1. Gen inhibits fructose-1,6-bisphosphatase. F16BP ATP AOP The fructose-1,6-bisphosphatase reaction is exergonic. D) The phosphofructokinase-1 reaction is endergonic. This regulation allows control of the direction of net metabolite flow through the pathway.
