So N link glycosylation between the sparring and that respective oligosaccharide begins at the endoplasm reticulum and is completed at the Golgi apparatus. On the other hand, the old linkages are only formed exclusively and entirely inside the Golgi apparatus. Now, to see exactly how the process takes place, let's take a look at this diagram. And let's begin on the endoplasmic reticulum. So along the outer membrane of this or along the outer section of the membrane of the endoplasm reticulum. So on the cytoplasmic side.
