A hormone not involved in sugar metabolism is

Options

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

Answer

To determine which hormone is not involved in sugar metabolism, let's analyze the options provided:

1. **Glucagon**:
- **Source**: Released from the alpha cells of the pancreas.
- **Function**: Increases blood glucose levels by promoting the conversion of glycogen to glucose in the liver when blood sugar levels are low.
- **Conclusion**: Involved in sugar metabolism.

2. **Cortisol**:
- **Source**: Released from the adrenal cortex.
- **Function**: A glucocorticoid that helps break down glycogen into glucose, thereby increasing blood glucose levels.
- **Conclusion**: Involved in sugar metabolism.

3. **Aldosterone**:
- **Source**: Released from the adrenal cortex.
- **Function**: A mineralocorticoid that primarily regulates sodium and potassium levels, promoting sodium reabsorption in the kidneys.
- **Conclusion**: Not involved in sugar metabolism.

4. **Insulin**:
- **Source**: Released from the beta cells of the pancreas.
- **Function**: Lowers blood glucose levels by facilitating the uptake of glucose into cells when blood sugar levels are high.
- **Conclusion**: Involved in sugar metabolism.

Based on the analysis, the hormone that is not involved in sugar metabolism is **Aldosterone**.

### Final Answer: Aldosterone
