Question

The hormone which regulates the basal metabolism in our body is secreted from?

• A. Pancreas
• B. Adrenal cortex
• C. Thyroid
• D. Pituitary gland

Answer 1

The correct option is C

Thyroid

The correct option is C.

Explanation of the correct option:

1. The thyroid hormone regulates the basal metabolic rate of the body.
2. Tetraiodothyronine, often known as thyroxine (T₄), and triiodothyronine are two hormones that the thyroid gland produces (T₃).
3. Iodine levels in the body control the synthesis of these hormones.
4. The metabolism of proteins, lipids, and carbohydrates is controlled by thyroid hormones.
5. The thyroid hormones are also important for controlling the balance of water and electrolytes.

Explanation of the incorrect options:

Option A:

1. Pancreas: It is both an exocrine and endocrine gland.
2. It produces enzymes that are released in the duodenum and are known as pancreatic juice.
3. The endocrine pancreas produces glucagon, insulin, and somatostatin as its primary hormones.
4. The hormone glucagon signals the liver and muscle cells to convert the glycogen back into glucose so that the other cells can easily absorb it and produce energy.
5. When blood glucose levels are high, insulin inhibits the hydrolysis of glycogen into glucose in the liver and muscles.
6. Somatostatin, also known as GHIH (growth inhibiting hormone), helps in controlling the balance of salt or blood sugar.
7. These hormones are responsible for maintaining the sugar level of the blood.
8. Hence, it is an incorrect option

Option B:

1. The adrenal cortex produces androgens, which are responsible for the development of facial hair, pubic hair, etc.
2. The adrenal cortex also produces the female sex hormone known as estrogen.
3. It regulates female sexual and reproductive development, including the development of female characteristics like the development of breasts.
4. Hence, it is an incorrect option

Option D:

1. The pituitary gland is the master gland. It releases hormones that control the activities of other endocrine glands.
2. Hence, it is the incorrect option.

Final answer: The hormone which regulates the basal metabolism in our body is secreted from the thyroid gland.
