Question

prokaryotic eukaryotic cells amino acid chain (protein) trna mrna codon large subunit ribosome cell wall mitochondrion smooth endoplasmic reticulum select ____ is the cellular site for protein synthesis.

Explanation:

To determine the cellular site for protein synthesis, we analyze the options:

• Ribosome: Known to be the site where translation (protein synthesis) occurs, using mRNA, tRNA, and assembling amino acids into a chain.
• Cell wall: Provides structural support, not involved in protein synthesis.
• Mitochondrion: Generates ATP, has its own protein synthesis but the question refers to the main site in the context (and ribosome is the primary site for general protein synthesis).
• Smooth endoplasmic reticulum: Involved in lipid synthesis, not protein synthesis (rough ER has ribosomes for protein synthesis, but the option here is smooth ER).

So the correct choice is ribosome.

Answer:

ribosome
