👉 Glycogen is a type of carbohydrate that is stored in the liver and muscles for energy. It is composed of two molecules of glucose, each linked to two phosphate groups, forming a sugar-phosphate backbone. The process of glycolysis involves the breakdown of glucose into pyruvate and the release of energy through the Krebs cycle. Glycogenase, also known as glycogen synthase or glycogen phosphorylase, is an enzyme that catalyzes this biochemical
