Which of the following hormones promotes glycogenolysis?

Solution
The correct option is B Glucagon
Glucagon increases blood glucose levels. It acts mainly on the liver cells (hepatocytes) and stimulates the breakdown of glycogen to form glucose (glycogenolysis) resulting in an increased blood sugar level. It also stimulates the process of gluconeogenesis, i.e., formation of glucose from non-carbohydrate sources.
Insulin, on the other hand, decreases blood glucose levels. It stimulates conversion of glucose to glycogen (glycogenesis) in its target cells.
Adrenaline and noradrenaline are secreted by the adrenal medulla in response to emergency situations.
Aldosterone is a mineralocorticoid released by the adrenal cortex. It regulates the balance of water and electrolytes in the body.
