WebApr 16, 2024 · The distinction is that hydrolysis reactions use water to cleave bigger molecules into smaller ones, but phosphorolysis reactions use phosphate instead for the same purpose. Note that the phosphate is just that - it does NOT come from ATP. Since ATP is not used to put phosphate on G1P, the reaction saves the cell energy. WebGlycogenolysis is the breaking of these bonds to release glucose molecules. Glycogen phosphorylase works by adding a phosphate to break the alpha 1,4 glycoside bonds. This results in glycogen forming into glucose 1 phosphate which is then made into glucose 6 phosphate to be used in the various pathways. helphelp893838 • 1 min. ago.
