[{'content': 'Intracellular soing and packing done by \nSelect and explain. \nA. ER, B. Golgi apparatus, C. Ribosome, D. Cytoplasm', 'role': 'user'}, {'content': 'Answer: B \nExplanation: 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', 'role': 'assistant'}]
