Question

Hormone that is not involved in sugar metabolism is

• A. Glucagon
• B. Cortisol
• C. Insulin
• D. Aldosterone

Hint:

If the hormone is involved in regulating glucose levels (like insulin or glucagon), it is linked to sugar metabolism. Aldosterone regulates minerals, not sugar.

Answer 1

The Correct Option is D

Sugar metabolism is primarily regulated by hormones such as insulin, glucagon, and cortisol:
- Insulin lowers blood glucose levels by promoting its uptake into cells.
- Glucagon raises blood glucose levels by promoting glycogen breakdown in the liver.
- Cortisol increases blood glucose levels by stimulating gluconeogenesis.
Aldosterone, on the other hand, is a mineralocorticoid hormone secreted by the adrenal cortex. It plays a key role in regulating sodium and potassium balance and maintaining blood pressure. It is not directly involved in carbohydrate (sugar) metabolism.
Therefore, the correct answer is Aldosterone.

Answer 2

Hormones play crucial roles in regulating sugar metabolism, maintaining blood glucose levels, and ensuring energy supply to the body. Important hormones involved in sugar metabolism include insulin, glucagon, cortisol, and adrenaline. These hormones either lower or raise blood glucose levels depending on the body's needs.

Insulin, produced by the pancreas, lowers blood sugar by facilitating glucose uptake into cells. Glucagon, also from the pancreas, raises blood glucose by promoting glycogen breakdown in the liver. Cortisol and adrenaline increase blood sugar during stress by stimulating glucose production and mobilization.

Aldosterone, on the other hand, is a steroid hormone produced by the adrenal cortex that primarily regulates sodium and potassium balance in the body and helps control blood pressure. It acts on the kidneys to increase sodium reabsorption and potassium excretion but does not have a direct role in sugar metabolism.

Therefore, among the hormones, aldosterone is the one not involved in sugar metabolism.
