The correct sequence for the process of secretion by the Golgi apparatus starts with products from the rough endoplasmic reticulum (RER) being packaged into transport vesicles (3), followed by these vesicles arriving at the forming face of the Golgi apparatus (5). Enzymes within the Golgi apparatus then modify the arriving proteins and glycoproteins (6). As the Golgi apparatus matures, its cisternae move from the forming face toward the maturing face (1), where secretory vesicles are formed (4). Finally, these vesicles undergo exocytosis to release their contents outside the cell (2).
