Penicillin has inhibitory effect on bacteria through:

Options

A. Stopping entrance of antibody
B. By causing death by destruction of nucleus
C. Inhibition of cell wall formation
D. None of the above

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Penicillin**: Penicillin is an antibiotic that was the first to be discovered. It is produced by certain microorganisms, particularly fungi of the genus Penicillium.

2. **Mechanism of Action**: The primary way penicillin exerts its inhibitory effect on bacteria is through the disruption of bacterial cell wall synthesis.

3. **Inhibition of Cell Wall Synthesis**: Penicillin targets the enzymes involved in the synthesis of peptidoglycan, which is a crucial component of the bacterial cell wall. By inhibiting these enzymes, penicillin prevents the bacteria from forming a proper cell wall.

4. **Resulting Effect**: Without a functional cell wall, bacteria cannot maintain their structural integrity. This leads to cell lysis (bursting) and ultimately the death of the bacteria.

5. **Conclusion**: Therefore, penicillin inhibits bacteria primarily by disrupting their cell wall synthesis, leading to cell death.
