Glycogen Metabolism | Glycogenolysis | Pathway, Enzymes and Regulation

The video tutorial covers glycogenolysis, explaining its advantages as a rapid energy source and its ability to generate ATP anaerobically. It also discusses the disadvantages, such as limited ATP yield per mass and storage capacity. The roles of glycogen in muscle and liver are highlighted, with a focus on energy provision and blood glucose maintenance. Key enzymes like glycogen phosphorylase and debranching enzyme are detailed, along with their regulatory mechanisms involving insulin and glucagon. Differences in glycogen metabolism between liver and muscle are explored, emphasizing gluconeogenesis and glycolysis. The tutorial concludes by explaining why glycogen yields more ATP compared to non-glycogen glucose.
