The synthesis of membrane proteins is completed in both the smooth endo retic for the lipid tails and the rough endo retic for the rest of the phospholipid structure. Proteins are transported to the golgi apparatus in vesicles (membranous sacs) and bud off of the golgi apparatus in vesicles as well. The vesicle then fuses with the membrane and releases its contents.
