Lysozyme kills bacteria by destroying

Options

A. DNA
B. Lipid bilayers
C. Cell wall
D. Mitochondrial enzymes

Answer

**Step-by-Step Solution:**

1. **Understanding Lysozyme**: Begin by recognizing that lysozyme is an enzyme that plays a crucial role in the immune system by protecting the body from bacterial infections.

2. **Function of Lysozyme**: Lysozyme specifically targets bacteria. It does this by attacking the protective structures of bacterial cells.

3. **Bacterial Cell Walls**: Bacteria have a tough outer layer known as the cell wall, which is primarily composed of carbohydrate chains that are interlinked by short peptide chains. This structure provides rigidity and protection to the bacterial cell.

4. **Mechanism of Action**: When lysozyme encounters bacteria, it breaks down the components of the bacterial cell wall. This action disrupts the structural integrity of the cell wall.

5. **Result of Action**: As the structural integrity of the cell wall is compromised, the bacteria can no longer maintain their shape and integrity, leading to their rupture or bursting.

6. **Conclusion**: Therefore, lysozyme kills bacteria by destroying their cell walls.

7. **Final Answer**: The correct answer is that lysozyme kills bacteria by destroying the **cell wall**.
