WebThe process of breakdown of glycogen to yield glucose residues is called glycogenolysis. Glycogen acts as a source of glucose providing it when the body needs it. The process … WebThe first enzyme is glycogen phosphorylase (GP). The job of this enzyme is to break down glycogen into glucose. Glycogen is a storage form of glucose, and when energy is needed, glycogen must be broken down. Phosphorylation activates glycogen phosphorylase, causing lots of glucose to be released.
