Phosphofructokinase is a key enzyme controlling the rate of glycolysis, as the reaction product it catalyzes is intended for glycolysis only. A. Explain in detail the effect of different concentrations of ATP on the activity of the enzyme phosphofructokinase as implied by the figure in front of you: B. Explain in detail the effect of different concentrations of fructose 2,6 bisphosphate on the activity of the phosphofructokinase enzyme as implied by the figure below: C. In your opinion what do you think will be the effect of fructose 2,6 bisphosphate on the enzyme fructose 1,6 bisphosphatase-1? Elaborate on your
