The wall of bacteria consists of

Options

A. N-acetylglucosamine
B. N-acetyl muramic acid
C. Both ( a ) and ( b)
D. Cellulose

Answer

To answer the question about the composition of the bacterial cell wall, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Composition of the Bacterial Cell Wall**:
- The bacterial cell wall is primarily composed of a substance known as peptidoglycan.

2. **Understand the Components of Peptidoglycan**:
- Peptidoglycan itself is made up of two main components:
- **N-acetyl muramic acid** (often abbreviated as NAM)
- **N-acetyl glucosamine** (often abbreviated as NAG)

3. **Analyze the Options Given**:
- The question likely provides multiple-choice answers. Based on the information we have:
- Option A: N-acetyl glucosamine (correct)
- Option B: N-acetyl muramic acid (correct)
- Option C: Cellulose (incorrect, as cellulose is not a component of bacterial cell walls)

4. **Select the Correct Answer**:
- Since both N-acetyl glucosamine and N-acetyl muramic acid are components of peptidoglycan, the correct answer would be the option that includes both A and B.

5. **Conclusion**:
- Therefore, the correct answer is option number 3, which states that the bacterial cell wall consists of both N-acetyl glucosamine and N-acetyl muramic acid.
