Fructose 16bisphosphate while fructose 26 bisphosphate A is

Fructose 1,6-bisphosphate_________, while fructose 2,6 bisphosphate_______.

A. is the product of PFK1, is the substrate of PFK2

B. activates PFK1, activates PFK2

C. isthe products of PFK1, activates pKF1

D. is the substrate of PFK1, is the substrate of PFK2

Solution

fructose 1,6- bisphosphate is the product of PFK1, while fuctose 2,6- bisphosphate activates PFK1.

Here fructose 1,6-bisphosphate is the potent and allosteric regulator of glycolysis and gluconeogenesis.

Hence the correct option is option C.
