Application of penicillin on bacterial cell inhibit the synthesis of

Options

A. DNA
B. RNA
C. Wall
D. Protein

Answer

To answer the question regarding the application of penicillin on bacterial cells and what synthesis it inhibits, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Penicillin**: Penicillin is an antibiotic that is produced naturally and is known for its ability to combat bacterial infections. It works specifically by targeting certain structures in bacterial cells.

2. **Identifying the Target of Penicillin**: The primary target of penicillin is the bacterial cell wall. Bacterial cell walls are composed of a polymer called peptidoglycan, which provides structural integrity to the cell.

3. **Mechanism of Action**: Penicillin inhibits the enzymes responsible for forming peptide cross-links in the peptidoglycan layer. These cross-links are crucial for the strength and rigidity of the cell wall.

4. **Effect of Inhibition**: When penicillin is applied to bacteria, the synthesis of the cell wall is disrupted. Without the formation of these peptide cross-links, the cell wall cannot be properly constructed.

5. **Consequences of Cell Wall Disruption**: As a result of the inhibited cell wall synthesis, the bacterial cell becomes a protoplast, which is a fragile structure that is highly susceptible to lysis (breaking apart). This makes the bacteria vulnerable to osmotic pressure and leads to cell death.

6. **Conclusion**: Therefore, the application of penicillin on bacterial cells inhibits the synthesis of the cell wall.

### Final Answer:
The application of penicillin on bacterial cells inhibits the synthesis of the **cell wall**.
