Which of the following is related to obesity, low plasma Na${}^{+}$, high K${}^{+}$ and increased blood pressure?

• A. Growth hormone
• B. Cortisol
• C. Thyroxine

Answer 1

The correct option is B Cortisol

A. GH (Growth hormone) is secreted from anterior lobe of pituitary gland and stimulates body growth and carbohydrate, protein, fat metabolism.

B. Cortisol is a glucocorticoid secreted from adrenal cortex. It stimulates water reabsorption from renal tubules and also maintains electrolytic balance (sodium and potassium concentration) in the body. It also regulates carbohydrate metabolism and promotes formation of glycogen and its storage.

C. Thyroxine is secreted from thyroid gland. It stimulates the consumption of oxygen by metabolically active tissues and also increases the oxidation of glucose in tissues.

D. Melatonin is secreted from pineal gland. It regulates circadian rhythm of body and pigmentation.

So, the correct answer is 'Cortisol'.
