Which cell organelle is the site of protein synthesis?

Single correct option

Which cell organelle is the site of protein synthesis?
  1. A. Lysosome
  2. B. Ribosome
  3. C. Mitochondria
  4. D. Vacuole
Show answer and solution

Answer: (B) Ribosome

Ribosomes read messenger RNA and join amino acids into proteins, either free in the cytoplasm or attached to the rough endoplasmic reticulum. Lysosomes digest waste, mitochondria produce ATP, and vacuoles store water and other substances. Because rough ER looks studded with ribosomes, it is a close distractor but it is not itself the site.
