Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.
Explanation:
The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.
There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
