WebEach is regulated by phosphorylation/dephosphorylation and by binding of other molecules. Phosphorylation of glycogen synthase switches it to the inactive, or "b " … WebOct 4, 2024 · Figure 8.3.1: Phosphorylation of glucose. Phosphorylation typically modifies the interaction of a substrate with its surroundings. It could be that phosphorylation, and the negative charge that results on the glucose, helps the glucose to bind more tightly with the next enzyme in the pathway.
