Bacterial cell membrane has

Options

A. Chitin
B. Cellulose
C. Proteins and phospholipids
D. Acetyl glucosamine and muramic acid

Answer

### Step-by-Step Solution:

1. **Identify the Type of Organism**:
- Bacteria are classified as prokaryotic organisms. This means they have a simpler cell structure compared to eukaryotic organisms.

2. **Understand the Structure of Bacterial Cells**:
- Bacterial cells have a cell wall and a cell membrane. The cell wall is primarily made of peptidoglycan, which provides structural support.

3. **Focus on the Bacterial Cell Membrane**:
- The bacterial cell membrane is crucial for maintaining the integrity of the cell and regulating the movement of substances in and out of the cell.

4. **Composition of the Bacterial Cell Membrane**:
- The bacterial cell membrane is composed of approximately 40% phospholipids and 60% proteins. This composition is essential for its function.

5. **Eliminate Incorrect Options**:
- Chitin is found in the cell walls of fungi, not bacteria.
- Cellulose is found in the cell walls of plants, not bacteria.
- Acetylglucosamine and muramic acid are components of the bacterial cell wall, not the cell membrane.

6. **Conclude with the Correct Answer**:
- The correct answer is that the bacterial cell membrane is composed of phospholipids and proteins.

### Final Answer:
The bacterial cell membrane has phospholipids and proteins.
