Understand the role of each organelle listed in the options with respect to protein synthesis.
Ribosomes are the sites of protein synthesis where mRNA is translated into polypeptide chains.
The Endoplasmic Reticulum (ER), specifically the rough ER, is involved in protein synthesis and folding, as it is studded with ribosomes.
The Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion or use within the cell, but it does not synthesize proteins.
Mitochondria are primarily involved in energy production through cellular respiration and are not directly involved in protein synthesis.
