STEP 1STEP 1Proteins and lipids Proteins and lipids that are made on that are made on the ER membranes the ER membranes are transported are transported through the ER and through the ER and are packaged in are packaged in transport vesicles transport vesicles that bud off from that bud off from the ER. the ER.
STEP 2STEP 2The vesicles fuse The vesicles fuse with the membrane with the membrane of the Golgi bodies, of the Golgi bodies, dumping their dumping their contents into the contents into the Golgi.Golgi.
STEP 3STEP 3Once inside the Once inside the Golgi bodies, the Golgi bodies, the molecules take one molecules take one of many paths. of many paths. Many become Many become tagged with tagged with carbohydrates.carbohydrates.
STEP 4STEP 4The molecules The molecules collect at the ends collect at the ends of the fold in the of the fold in the Golgi bodies. Golgi bodies. Vesicles pinch off Vesicles pinch off and carry the and carry the molecules to other molecules to other parts of the cell parts of the cell oror to the plasma to the plasma membrane where membrane where they will be they will be secreted to the secreted to the outside of the celloutside of the cell
