BIOMOLECULES AND ENZYMES

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: -Hydrolysis. Water molecules are required to break down glycogen into glucose molecules. At first, glycogen is broken down into glucose-6-phosphate and then converted to glucose-1-phosphate. Glucosidase enzymes hydrolyze the exposed branching site of glycogen.

Detailed explanation-3: -The liver supplies sugar or glucose by turning glycogen into glucose in a process called glycogenolysis. The liver also can manufacture necessary sugar or glucose by harvesting amino acids, waste products and fat byproducts.

Detailed explanation-4: -After a meal, glucose enters the liver and levels of blood glucose rise. This excess glucose is dealt with by glycogenesis in which the liver converts glucose into glycogen for storage. The glucose that is not stored is used to produce energy by a process called glycolysis. This occurs in every cell in the body.

Detailed explanation-5: -Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.
