First step in glycogen breakdown
WebGlycogen Breakdown Glycogenolysis is catalyzed by two enzymes unique to the pathway: glycogen phosphorylase and debranching enzyme. The former normally regulates the rate of glucose release from glycogen. The progressive degradation of glycogen is illustrated in Figure 14.8.
