The antibiotic inhibiting cell wall formation in bacterial cell is

Options

A. Clavicin
B. Pencillin
C. Ergotine
D. None of the above

Answer

To solve the question "The antibiotic inhibiting cell wall formation in bacterial cell is", we need to analyze the options provided and identify which antibiotic specifically targets the cell wall synthesis in bacteria.

### Step-by-Step Solution:

1. **Understand the Role of Antibiotics**:
- Antibiotics are substances that inhibit the growth of or kill bacteria. Different antibiotics have different mechanisms of action.

2. **Evaluate Each Option**:
- **Option 1: Clavicin**:
- Clavicin is an antibiotic, but it does not inhibit cell wall formation directly. Instead, it acts by rupturing the already formed cell wall, which is not the mechanism we are looking for.
- **Option 2: Penicillin**:
- Penicillin is a well-known antibiotic that specifically inhibits the enzyme transpeptidase, which is crucial for the synthesis of the bacterial cell wall. By inhibiting this enzyme, penicillin prevents the formation of the cell wall, leading to bacterial cell lysis and death. This is the correct answer.
- **Option 3: Ergotin**:
- Ergotin is not an antibiotic that targets bacteria; it is used for inducing uterine contractions and does not relate to bacterial cell wall synthesis.
- **Option 4: None of the above**:
- Since we have identified penicillin as the correct option, this choice is incorrect.

3. **Conclusion**:
- After evaluating all the options, the antibiotic that inhibits cell wall formation in bacterial cells is **Penicillin** (Option 2).

### Final Answer:
The antibiotic inhibiting cell wall formation in bacterial cell is **Penicillin** (Option 2).
