Begin by understanding the function of each organelle listed in the options. This will help you identify which one is responsible for protein synthesis.
Ribosomes are the organelles where protein synthesis occurs. They translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.
Lysosomes are involved in digestion and waste processing within the cell, not protein synthesis.
Mitochondria are known as the powerhouses of the cell, responsible for producing ATP through cellular respiration, not directly involved in protein synthesis.
The Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion or use within the cell, but it does not synthesize proteins.
