And once that forms, they basically move into the Golgi apparatus. So the proteins move out of the lumen of the Er and into the cytoplasm, where they then travel into the Golgi apparatus via these special transport vesicles. And inside the Golgi complex, the end link sugars are modified and the oglycosylation actually takes place. And once the Golgi complex modifies and sorts the glycoproteins, it then directs these glycoproteins to basically move into different locations depending on what their function actually is. And so they can end up in the lysosomes, they can end up being stored in secretary granules, or they can be stored in the bilayer membrane around that particular cell. So we see that glycoproteins are a very important class of biological molecules.
