WebNov 1, 2024 · Glycogen Metabolism . The two main metabolic pathways of glycogen are glycogenesis and glycogenolysis. In short, glycogenesis is the formation of glycogen from glucose molecules. Glycogenolysis, on the other hand, is the breakdown of glycogen into glucose molecules. WebWhen insulin levels in blood fall, glycogen synthesis in the liver diminishes and enzymes responsible for breakdown of glycogen become active. Glycogen breakdown is stimulated not only by the absense of insulin but by the presence of glucagon, which is secreted when blood glucose levels fall below the normal range. Insulin and Lipid …
