Question

Which hormone regulates the ionic balance in the body?
(a) Glucagon
(b) Thyroxine
(c) Testosterone
(d) Vasopressin

Answer 1

Hint: Glucagon arises from proglucagon.
Vasopressin is also known as antidiuretic hormone.

Complete Answer:
Glucagon is a peptide hormone that is produced by the alpha cells present in the pancreas. The main function of glucagon is to raise the concentration of fatty acids and glucose in the bloodstream. Glucagon is considered to be the primary catabolic hormone of the body. Glucagon also serves as medication for various health disorders. Glucagon functions contrary to insulin by increasing the concentration of glucose in the bloodstream.
Thyroxine is one of the two thyroid hormones produced by the thyroid gland of the body. The other thyroid hormone is triiodothyronine. Thyroxine is partially composed of iodine. A deficiency in the concentration of iodine in the body leads to a decrease in the production of thyroxine.
Testosterone is the main sex hormone in male organisms. Testosterone is also the primary anabolic steroid in males. Testosterone plays an important role in the development of reproductive tissues like testes and the prostate region in human males.
Vasopressin is a pituitary gland hormone. Vasopressin has two main functions:
- Vasopressin increases the amount of water reabsorbed in the body.
- Vasopressin constricts the arterioles which increases the blood pressure

Therefore, vasopressin maintains the ionic balance in the body. Hence, the correct answer is (d) Vasopressin

Note:
The decreased production of the thyroid hormones causes an inflammation in the thyroid tissue and leads to a disease called goitre.
Testosterone promotes the growth of secondary sexual characteristics in human males. These secondary sexual characteristics include the growth of facial hair, muscle mass and bone mass.
