Intracellular soing and packing done by

The Golgi apparatus plays two major roles in protein synthesis. First, it is involved in the processing of the oligosaccharide chains of membrane and other N-linked glycoproteins and also contains enzymes involved in O-glycosylation.Second, it is involved in the soing of various proteins prior to their delivery to their appropriate intracellular destinations.All pas of the Golgi apparatus paicipate in the first role, whereas the trans-Golgi network (TGN) is paicularly involved in the second and is very rich in vesicles.Ref: Harper 30th edition pg: 608
