Bacterial cell membrane has

Options

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

Answer

To answer the question "Bacterial cell membrane has," we will analyze the options provided and determine which components are present in the bacterial cell membrane.

### Step-by-Step Solution:

1. **Understand the Structure of Bacteria**:
- Bacteria are unicellular organisms and are classified as prokaryotes. This means they lack a defined nucleus and membrane-bound organelles.

2. **Identify the Components of the Bacterial Cell**:
- Bacteria have a cell wall that surrounds the cell membrane. The cell membrane is crucial for maintaining the integrity of the cell and regulating the movement of substances in and out of the cell.

3. **Examine the Options**:
- **Option A: Chitin** - Chitin is a polysaccharide found in the exoskeletons of insects and fungi, not in bacterial cell membranes.
- **Option B: Cellulose** - Cellulose is a structural component of plant cell walls, not found in bacteria.
- **Option C: Proteins and Phospholipids** - This option is correct. The bacterial cell membrane is primarily composed of a phospholipid bilayer with embedded proteins.
- **Option D: Acytolucosamide and Muramic Acid** - These compounds are not components of the bacterial cell membrane; they are related to the bacterial cell wall structure.

4. **Conclusion**:
- After analyzing all the options, the correct answer is **Option C: Proteins and Phospholipids**. These components are essential for the structure and function of the bacterial cell membrane.

### Final Answer:
Bacterial cell membrane has **Proteins and Phospholipids** (Option C).
