The breakdown of glycogen into glucose is called glycogenolysis. In glycogenolysis, there is the catabolism of glycogen by removal of a glucose monomer through cleavage with inorganic phosphate to produce glucose-1-phosphate. This derivative of glucose is then converted to glucose-6-phosphate, an intermediate in glycolysis. Glycogenolysis is regulated by the enzyme glycogen phosphorylase. It facilitates the quick retrieval of glucose molecules when extra energy is needed.The hormones glucagon and epinephrine stimulate glycogenolysis.
