Question

Which hormone controls water and mineral metabolism?

• A. Insulin
• B. Progesterone
• C. Glucagon
• D. Deoxycorticosterone

Answer 1

Answer: (D)

Deoxycorticosterone

A.Insulin is secreted from the β cells of islets of Langerhans of pancreas. Insulin acts on hepatocytes and adipocytes and increases the uptake of cellular glucose and its utilisation. This leads to movement of glucose to hepatocytes and adipocytes from the blood, thereby resulting in the decreased blood glucose levels.

B. Progesterone is a steroid female sex hormone which is also known as pregnancy hormone. It maintains the inner lining of uterus which aids in implantation of embryo in the uterus.

C. Glucagon is secreted from alpha cells of islets of Langerhans of pancreas. It increases blood sugar level by stimulating glycogenolysis (i.e. break down of glucose) and gluconeogenesis (synthesis of glucose).

D. Deoxycorticosterone is a steroid hormone secreted from adrenal gland and has mineralocorticoid activity. It stimulates water reabsorption from renal tubules and also maintains electrolytic balance in the body.

Hence, deoxycorticosterone controls water and mineral metabolism.

So, the correct answer is 'Deoxycorticosterone'.
