WebHow does ATP regulate glycolysis? The most important regulatory step of glycolysis is the phosphofructokinase reaction. … ATP inhibits the phosphofructokinase reaction by raising the K m for fructose6phosphate. AMP activates the reaction. Thus, when energy is required, glycolysis is activated. What are the 10 steps in glycolysis? WebBecause this enzyme promotes the forma-tion of fructose-1,6-diphosphate, one of the initial steps in the glycolytic series of reactions, the net effect of excess cellular ATP is to slow or even stop glycolysis, which in turn stops most carbohydrate metabolism. Conversely, ADP (and AMP as well) causes the oppo-site change in this enzyme, greatly ...
