Question

Hormone connected with increased rate of glycogenolysis, blood pressure and heart beat is:
A. Insulin
B. Glucagon
C. Adrenaline
D. FSH

Answer 1

Hint: Glycogenolysis refers to the process of formation of glycogen to be stored in liver and muscle cells. It helps to conserve excess glucose for emergency conditions. It also helps to maintain an optimum blood sugar level.

Complete Step by Step Answer:
Insulin is a hormone secreted by Islets of Langerhans from the pancreas. It stimulates the entry of glucose into cells for energy requiring processes whenever required. It is stored in the form glycogen in such cells, a process called glycogenolysis. This brings about a decrease in blood sugar level than before as the excess glucose is used by cells rather than entering the bloodstream.

Glucagon is another hormone secreted by the pancreas. It acts on the liver for stimulation of breakdown of glycogen into glucose. It also triggers a process called gluconeogenesis, that is, breakdown of amino acid to form glucose.

Adrenaline is a hormone responsible for fight or flight response. It causes vasoconstriction and directs blood especially to those areas that require instant and great amounts of energy. Thus it is also called a stress hormone.

FSH or Follicle stimulating hormone, by the name suggests, helps in the formulation of follicle in females. In males, it helps in production of sperms.

Thus, the correct answer is A: Insulin

Note: The Insulin is secreted by alpha cells of the pancreas while Glucagon is secreted by the beta cells of the pancreas. Insulin lowers the blood sugar level while glucagon increases the blood sugar level. Thus, both the hormones work to maintain a balance of the blood sugar level. For Type 1 Diabetes( Diabetes mellitus), Insulin is required.
