Perspiration contains an enzyme that kills bacteria. The enzyme is:

Options

A. Lipase
B. Lysozyme
C. Protease
D. Reductase

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about an enzyme present in perspiration (sweat) that has antibacterial properties.

2. **Identifying the Options**: The options provided are:
- Lipase
- Lysozyme
- Protease
- Reductase

3. **Analyzing Each Option**:
- **Lipase**: This enzyme is responsible for breaking down fats. It does not have antibacterial properties.
- **Lysozyme**: This is an antimicrobial enzyme that can kill bacteria. It is found in various bodily secretions, including sweat.
- **Protease**: This enzyme breaks down proteins. Like lipase, it does not have antibacterial properties.
- **Reductase**: This enzyme is involved in reduction reactions, such as the synthesis of fructose from glucose. It does not relate to antibacterial activity.

4. **Conclusion**: Based on the analysis, the enzyme that kills bacteria in perspiration is **lysozyme**.

5. **Final Answer**: The correct answer is **lysozyme**.
