In relation to insulin, Zinc is required for

Options

A. Synthesis of insulin
B. Release of insulin
C. Activity of insulin
D. Breakdown of insulin.

Answer

### Step-by-Step Solution:

1. **Understanding the Role of Zinc**:
- Zinc is an essential trace element that plays a crucial role in various biological functions, including hormone secretion.

2. **Identifying the Hormone in Question**:
- The question specifically mentions insulin, which is a hormone produced by the pancreas that regulates glucose levels in the blood.

3. **Analyzing the Options**:
- The options provided are:
- Option 1: Synthesis of insulin
- Option 2: Release of insulin
- Option 3: Activity of insulin
- Option 4: Breakdown of insulin

4. **Evaluating Each Option**:
- **Option 1 (Synthesis of insulin)**: Zinc is not directly involved in the synthesis of insulin; therefore, this option is incorrect.
- **Option 2 (Release of insulin)**: Zinc is known to aid in the secretion of insulin from the pancreas. It enhances the ability of insulin to bind to its receptors, facilitating its release into the bloodstream. This option is correct.
- **Option 3 (Activity of insulin)**: While zinc may influence insulin's effectiveness, it does not directly affect the activity of insulin itself. Thus, this option is incorrect.
- **Option 4 (Breakdown of insulin)**: Zinc is not involved in the breakdown of insulin, making this option incorrect as well.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option 2: Release of insulin**. Zinc is required for the secretion of insulin, which is crucial for maintaining glucose homeostasis.
