Enzyme for peptide formation is located in

Options

A. Smaller subunit of ribosome
B. Larger subunit of ribosome
C. tRNA
D. Cytoplasm

Answer

To answer the question regarding the location of the enzyme responsible for peptide formation, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Enzyme**: The enzyme responsible for peptide formation is called peptidyl transferase.

2. **Understand the Process**: Peptide formation occurs during the process of translation, which is part of protein synthesis. This process involves the assembly of amino acids into a polypeptide chain.

3. **Locate the Site of Translation**: Translation occurs in the ribosome, which is the cellular machinery responsible for synthesizing proteins.

4. **Structure of the Ribosome**: The ribosome consists of two subunits: a smaller subunit and a larger subunit.

5. **Identify the Location of Peptidyl Transferase**: Peptidyl transferase is located in the larger subunit of the ribosome. This is where it catalyzes the formation of peptide bonds between amino acids during translation.

6. **Conclusion**: Therefore, the enzyme for peptide formation (peptidyl transferase) is located in the larger subunit of the ribosome.

### Final Answer:
The enzyme for peptide formation is located in the larger subunit of the ribosome.
