Glycogenolysis is the breakdown of complex carbohydrate glycogen into glucose-1-phosphate, which may then be changed into glucose-6-phosphate and enter the glycolytic pathway to make ATP. Glycogenolysis is the breakdown of glycogen into glucose for energy. Learn where it occurs, how it works, and its functions and abnormalities. Glycogenolysis is a metabolic process that converts glycogen from the muscles and liver to its monosaccharide form, glucose. Glycogen is a glucose polysaccharide stored in the muscles and liver. Glycogenolysis is the enzymatic process of breaking down glycogen, a stored polysaccharide, into glucose-1-phosphate and glucose to provide energy or maintain blood sugar levels during fasting or increased energy demand.
