Question

Which one of the following hormone is a mineralocorticoid?

• A. Aldosterone
• B. Adrenaline
• C. Cortisol
• D. All of the above

Answer 1

The correct option is A Aldosterone

Mineralocorticoids regulate the balance of water and electrolytes in our body. Aldosterone is the main mineralocorticoid in our body. It acts on distal tubules of kidney and stimulates reabsorption of water and Na+ ions and excretion of K+ and phosphate ions. This restores water and mineral balance in our body.
Glucocorticoids are involved in carbohydrate metabolism. Cortisol is the main glucocorticoid in our body.
Adrenaline (also known as catecholamines) is secreted by adrenal medulla in response to stressful emergency situations and are called emergency hormones or hormones of fight or flight.
