When is PFK-2 activated and when is FBP activated?
When there is a high insulin to glucagon level there is low protein kinase A this leads to the dephosphorylation of the bifunctional enzyme and PFK-2 is activated this Frustose2,6,Bisphosphate can be created and Gycolysis is stimulated at step 3 seeing that F26bisphosphate is a potent activator of PFK-1 which is the rate-limiting step of glycolysis
