MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glucose. The reaction takes place in the hepatocytes and the myocytes. The process is under the regulation of two key enzymes: phosphorylase kinase and glycogen phosphorylase.

Detailed explanation-2: -In the lysosomes, the breakdown of glycogen is accomplished by the lysosomal enzyme acid -glucosidase or acid maltase (Fig. 4).
