Question

2 multiple choice 1 point the site of protein synthesis is cell membrane nucleus mitochondria ribosomes

Explanation:

• Cell membrane: Acts as a barrier and regulates substance passage, no role in protein synthesis.
• Nucleus: Stores genetic material (DNA), not the site of protein synthesis.
• Mitochondria: Produces ATP (energy currency of the cell), not related to protein synthesis.
• Ribosomes: Read mRNA (messenger RNA) and assemble amino acids into polypeptides (proteins).

Answer:

Ribosomes
