And if that enzymes activity is inhibited, it will stop producing the fructose one six bits phosphate and that will increase the concentration of fructose six phosphate. And this increase bilastritle edge principle will cause the increase in this glucose six phosphate and that creates a negative feedback loop and inhibits the activity of Hexokinase. Now if these two enzymes are inhibited then these two pathways are inhibited and that will basically turn off the process of glycolysis. On top of that, the ATP will also bind onto pyruvate kinase and inhibit the third process irreversible process of glycolysis. And so when we have high amounts of ATP all three irreversible processes are inhibited and glycolysis stops producing ATP. But on the other hand, if we're exercising very vigorously we're going to have a low energy charge value because of this process.
