Is glycogenesis and glycogenolysis the same?

No, glycogenesis and glycogenolysis are not the same; they are opposite processes. Glycogenesis is the process of synthesizing glycogen from glucose molecules for storage, primarily in the liver and muscle cells. This process occurs when there is an excess of glucose in the blood, and the body needs to store it for future use. On the other hand, glycogenolysis is the breakdown of glycogen into glucose to provide energy when blood glucose levels are low or during periods of increased energy demand, such as exercise. While glycogenesis builds glycogen, glycogenolysis breaks it down.
