Which one of the following matching pairs is WRONG

Options

A. Bacterial cell wall-Peptidoglycan
B. Bacterial ribosome-16 S rRNA
C. Bacteria flagella-Protein
D. Bacterial glycocaly -Cellulose

Answer

To determine which matching pair is wrong, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Analyze the First Pair: Bacterial Cell Wall - Peptidoglycan**
- The bacterial cell wall is primarily composed of peptidoglycan, which is a polymer consisting of sugars and amino acids.
- **Conclusion**: This statement is correct.

2. **Analyze the Second Pair: Bacterial Ribosome - 16s RNA**
- Bacterial ribosomes are made up of ribosomal RNA (rRNA) and proteins. The 16s rRNA is a component of the 30S ribosomal subunit in bacteria.
- **Conclusion**: This statement is correct.

3. **Analyze the Third Pair: Bacteria Flagella - Protein**
- Flagella in bacteria are indeed made up of a protein called flagellin. They are used for locomotion.
- **Conclusion**: This statement is correct.

4. **Analyze the Fourth Pair: Bacterial Glycocalyx - Cellulose**
- The bacterial glycocalyx is a layer surrounding the cell wall, composed mainly of polysaccharides. It does not contain cellulose.
- **Conclusion**: This statement is incorrect. The correct statement should be that bacterial glycocalyx is made up of polysaccharides.

### Final Answer:
The wrong matching pair is: **Bacterial Glycocalyx - Cellulose.**
