Intracellular organelles involved with protein synthesis include:

b. Endoplasmic reticulum

c. Golgi complex 

Mitochondria are the major source of energy production in eukaryotic cells. The endoplasmic reticulum is the network of interconnected membranes forming closed vesicles, tubules, and saccules. The endoplasmic reticulum has a number of functions and is primarily involved in the synthesis of proteins and lipids. Adjacent to the rough endoplasmic reticulum and functionally involved in the sorting and package of secreted protein is the Golgi complex. Lysosomes are membrane-limited organelles containing acid hydrolytic enzymes that degrade polymers such as proteins, carbohydrates, and nucleic acids.
