Out of the following hormones ; which one is not involved in carbohydrate metabolism

Options

A. Cortisone
B. Aldosterone
C. Insulin
D. Glucagon

Explanation

To determine which hormone is not involved in carbohydrate metabolism from the given options, we will analyze each hormone one by one.

### Step-by-Step Solution:

1. **Identify the Hormones**: We need to look at the hormones provided in the options. The options include cortisone, aldosterone, insulin, and glucagon.

2. **Analyze Cortisone**:
- Cortisone is a glucocorticoid hormone secreted by the adrenal cortex.
- It plays a role in carbohydrate metabolism by stimulating the liver to synthesize glucose from non-carbohydrate sources (gluconeogenesis).
- Therefore, cortisone is involved in carbohydrate metabolism.

3. **Analyze Aldosterone**:
- Aldosterone is a mineralocorticoid hormone also secreted by the adrenal cortex.
- Its primary function is to regulate sodium and potassium levels and maintain blood pressure and blood volume.
- Aldosterone does not directly influence carbohydrate metabolism.
- Hence, aldosterone is not involved in carbohydrate metabolism.

4. **Analyze Insulin**:
- Insulin is a hormone produced by the pancreas that lowers blood glucose levels.
- It facilitates the uptake of glucose by cells and promotes glycogenesis (the formation of glycogen from glucose).
- Thus, insulin is clearly involved in carbohydrate metabolism.

5. **Analyze Glucagon**:
- Glucagon is another hormone produced by the pancreas, which raises blood glucose levels by promoting glycogenolysis (the breakdown of glycogen into glucose) and gluconeogenesis.
- Therefore, glucagon is also involved in carbohydrate metabolism.

6. **Conclusion**:
- After analyzing all the hormones, we find that cortisone, insulin, and glucagon are involved in carbohydrate metabolism, while aldosterone is not.
- Thus, the hormone that is not involved in carbohydrate metabolism is **aldosterone**.

### Final Answer:
**Aldosterone** is the hormone that is not involved in carbohydrate metabolism.
