Lysozyme that is present in perspiration, saliva and tears destroys

Options

A. certain types of bacteria
B. all viruses
C. most virus-infec,ed cells
D. certain fungi

Answer

**Step-by-Step Solution:**

1. **Understanding Lysozyme**:
- Lysozyme is a natural enzyme found in various bodily secretions such as perspiration (sweat), saliva, and tears.

2. **Function of Lysozyme**:
- The primary function of lysozyme is to act as an antimicrobial agent. It specifically targets bacterial cells.

3. **Mechanism of Action**:
- Lysozyme destroys bacterial cells by breaking down the glycosidic bonds in the peptidoglycan layer of the bacterial cell wall. This action compromises the integrity of the bacterial cell wall, leading to cell lysis (destruction).

4. **Identifying What Lysozyme Destroys**:
- Since lysozyme is effective against bacteria, we can conclude that it destroys certain types of bacteria.

5. **Evaluating Options**:
- The question likely provides multiple-choice options. The correct answer would be the one that states that lysozyme destroys certain types of bacteria.
- Other options such as "all viruses," "most viruses," or "certain fungi" would be incorrect, as lysozyme does not target these pathogens.

6. **Final Answer**:
- Therefore, the final answer to the question is that lysozyme destroys certain types of bacteria.
