All of the following hormones are involved in sugar metabolism, expect

Options

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

Answer

To solve the question regarding which hormone is not involved in sugar metabolism, we can analyze the roles of the hormones mentioned.

**Step 1: Identify the hormones listed in the question.**
- Glucagon
- Cortisone
- Thymosine
- Insulin

**Step 2: Analyze the function of each hormone.**
1. **Glucagon**: This hormone is secreted by the pancreas and its primary function is to increase blood glucose levels. It plays a crucial role in sugar metabolism by promoting the conversion of glycogen to glucose in the liver.

2. **Cortisone**: This hormone is a type of corticosteroid and it increases the glucose requirement of the body. It also plays a role in glucose metabolism by influencing the metabolism of carbohydrates.

3. **Thymosine**: This hormone is produced by the thymus gland and is primarily involved in the development of T cells, which are essential for the immune system. It does not have a direct role in sugar metabolism.

4. **Insulin**: This hormone is also secreted by the pancreas and is responsible for lowering blood glucose levels by facilitating the uptake of glucose into cells. It plays a significant role in maintaining glucose homeostasis.

**Step 3: Determine which hormone is not involved in sugar metabolism.**
From the analysis, we can see that:
- Glucagon, cortisone, and insulin are all involved in sugar metabolism.
- Thymosine, on the other hand, is not involved in sugar metabolism as its primary function is related to immune response and T cell production.

**Conclusion:**
The hormone that is not involved in sugar metabolism is **Thymosine**.
