Glucose6-phosphate can also formribose 5-phosphate … WebIn the breakdown of glycogen, phosphorolysis is preferable to hydrolysis because glucose-1-phosphate provides more ATP than free glucose does when catabolized to pyruvate. A hydrolytic cleavage would produce glucose, which needs further phosphorylation at the expense of a molecule of ATP.
WebWhen glycogen synthesis is not needed, the phosphorylation of glycogen synthase occurs that prevents the action of the enzyme by changing its structure. Glycogen phosphorylase causes phosphorylation of glycogen that results in the formation of glucose-1-phosphate by the breakdown of glycogen.
