Question

Peptide synthesis inside a cell takes place in:

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

Answer 1

The correct option is A

Ribosomes

The correct option is A:

Explanation of the correct option:

1. Ribosomes are found in all cells.
2. They are the site of protein synthesis.
3. Protein or peptide synthesis is carried out with an mRNA template.
4. The ribosomes then translate the genetically coded information in the mRNA to synthesize proteins.

Explanation of the incorrect options:

Option B:

Pigments such as orange carotene, yellow xanthophylls, and various other red pigments are stored and synthesized in the chromoplasts.

Option C:

Oxidative phosphorylation occurs in the mitochondria to produce energy for the cell's survival and functioning.

Option D:

Photosynthesis occurs in the chloroplasts to provide the plant with food and energy.

Final answer: Peptide synthesis inside a cell takes place in the ribosomes.
