First step in glycogen breakdown

WebFeb 12, 2024 · Glycogenolysis is the breakdown of the molecule glycogen into glucose, a simple sugar that the body uses to produce energy. Glycogen is essentially stored energy in the form of a long chain of glucose, and glycogenolysis takes place in muscle and liver cells when more energy needs to be produced. 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.
