The bacterial cells can be lysed by using ………… enzyme.

Options

A. protease
B. lysozyme
C. lipase
D. cellulase

Explanation

To answer the question, "The bacterial cells can be lysed by using ………… enzyme," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Bacterial Cell Lysis**:
- Lysis refers to the breaking down or destruction of cells. In the context of bacterial cells, this process is crucial for various applications in biotechnology, such as extracting proteins or DNA.

2. **Identifying Enzymes**:
- The question provides a list of enzymes: proteases, lysozymes, lipase, and cellulase. We need to determine which of these enzymes is specifically effective at lysing bacterial cells.

3. **Analyzing Each Enzyme**:
- **Proteases**: These enzymes break down proteins but are not specifically known for lysing bacterial cells.
- **Lysozymes**: This enzyme specifically targets the peptidoglycan layer in bacterial cell walls, leading to cell lysis.
- **Lipase**: These enzymes break down lipids and are not effective for lysing bacterial cells.
- **Cellulase**: This enzyme breaks down cellulose, which is not a component of bacterial cell walls.

4. **Conclusion**:
- Based on the analysis, the enzyme that can effectively lyse bacterial cells is **lysozyme**.

5. **Final Answer**:
- The bacterial cells can be lysed by using **lysozyme** enzyme.
