The cell organelle that contains all the necessary enzymes to catalyse the formation ofpolypeptides by amino acids is
Correct answer: A. Ribosome
- A. Ribosome
- B. Lysosome
- C. Centrosome
- D. Peroxisome.
Explanation
The correct answer is Option A: ribosome. Ribosomes are responsible for synthesizing proteins by linking amino acids into polypeptide chains. They contain the necessary sites and enzymatic activity to facilitate this process. Option B, Lysosomes, are involved in digestion and waste processing, not protein synthesis. Option C, Centrosomes, are related to organizing microtubules during cell divisionOption D, Peroxisomes, handle oxidative reactions, neither of which is directly involved in the formation of polypeptides from Amino acids.
