Peptide synthesis inside a cell takes place in

Options

A. Ribosomes
B. Chloroplast
C. Mitochondria
D. Chromoplast

Answer

**Step-by-Step Solution:**

1. **Understanding Peptide Synthesis**: Peptide synthesis refers to the process of forming peptide bonds between amino acids to create proteins. This process is crucial for cellular function and structure.

2. **Identifying the Location of Synthesis**: The primary site of peptide synthesis in a cell is the ribosome. Ribosomes are often referred to as the "protein factories" of the cell because they are responsible for translating messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.

3. **Structure of Ribosomes**: Ribosomes are composed of ribosomal RNA (rRNA) and proteins. They exist in two subunits (large and small) that come together during protein synthesis.

4. **Role of Ribosomes in Peptide Bond Formation**: During the process of translation, ribosomes facilitate the formation of peptide bonds between adjacent amino acids. This occurs in the ribosome's active site, where tRNA molecules bring specific amino acids to the ribosome according to the sequence encoded in the mRNA.

5. **Conclusion**: Therefore, the correct answer to the question is that peptide synthesis inside a cell takes place in ribosomes.

**Final Answer**: Peptide synthesis inside a cell takes place in ribosomes.
