Which cellular structure is the location of protein synthesis in a eukaryotic cell?

The ribosome is the location of protein synthesis in a eukaryotic cell. Free ribosomes are located in the cytosol while other ribosomes are attached to the rough endoplasmic reticulum. The mitochondrion is the location of ATP synthesis during cellular respiration. The lysosome is responsible for the digestion of large biological molecules into smaller components. The Golgi apparatus is responsible for modifying and packaging materials for transport within the cell or for secretion from the cell.
