Proteins made by ER travel to the golgi in sacks called cistern. Golgi MODIFIES and PACKAGE proteins for export out of the cells.
The process of protein synthesis in cells occur in series of steps and involved three major cell organelles, which are nucleus, ribosomes and golgi apparatus. The golgi apparatus is responsible for modification, sorting and packaging of proteins. It determines which proteins are to be sent outside the cells and the ones that are to be retained by the cell
