Web16.1.1 Glycoprotein synthesis. Glycoprotein synthesis occurs in two organelles in sequence such as endoplasmic reticulum and the Golgi apparatus. The carbohydrate core is attached to the protein both co-translationally and post-translationally. The ribosome bearing the mRNA which codes for the proteins attaches to the endoplasmic reticulum. WebGolgi Apparatus. Recall that that vesicles can bud from the ER and transport their contents elsewhere, but where do the vesicles go? Before reaching their final destination, the lipids or proteins within the transport vesicles still need sorting, packaging, and tagging so that they wind up in the right place. Sorting, tagging, packaging, and distribution of lipids and …
