So we essentially attach those sugar molecules onto asparagine via the end linkage inside the endoplasm reticulum. Now, once we form the protein, the protein then leaves the endoplasm reticulum. It goes into a special transport vesicle that carries it onto this side, which is known as the cyst side of the Golgi apparatus. So, once on the CIS side of the Golgi apparatus, which is this side here, it basically moves along the Golgi apparatus. And as it moves, that particular N linked sugar molecule is even further modified. And on top of that, we also form the old glycosytic linkages between either the serene and threatening and that particular sugar molecule.
