Steroid hormone regulating glucose metabolism

Options

A. Cortisone
B. Cortisol
C. Corticosterone
D. 11- deoxycorticosterone.

Answer

### Step-by-Step Text Solution

1. **Identify the Hormones**: The question lists several steroid hormones: cortisone, cortisol, corticosterone, and 11-deoxycorticosterone. We need to determine which of these regulates glucose metabolism.

2. **Understanding 11-Deoxycorticosterone**: This hormone is produced by the adrenal gland and has mineralocorticoid activity. It acts as a precursor to aldosterone, which primarily regulates sodium and potassium levels, not glucose metabolism. Therefore, it is not the correct answer.

3. **Analyzing Corticosterone**: Corticosterone is another steroid hormone produced by the adrenal cortex. It plays a role in energy regulation, immune response, and stress response. However, it is not primarily known for regulating glucose metabolism.

4. **Examining Cortisol**: Cortisol is a glucocorticoid hormone produced by the adrenal cortex. It is released in response to stress and low blood glucose levels. Cortisol's primary function is to increase blood sugar levels through gluconeogenesis, which is the process of converting non-carbohydrate substrates into glucose. It also aids in the metabolism of fats, proteins, and carbohydrates.

5. **Reviewing Cortisone**: Cortisone is also a glucocorticoid hormone that can convert proteins into carbohydrates. While it does have some role in glucose metabolism, it is not as directly involved as cortisol.

6. **Conclusion**: Based on the functions of these hormones, cortisol is the primary steroid hormone that regulates glucose metabolism. Therefore, the correct answer to the question is cortisol.

### Final Answer
The steroid hormone regulating glucose metabolism is **Cortisol**.
