Ans. ‘A’ Golgi bodies.
Golgi Apparatus plays two major roles in protein synthesis. First, it is involved in the processing of the oligosaccharide chains of the membrane and other N-linked glycoproteins and also contains enzymes involved in O-glycosylation.
Second, it is involved in the sorting of various proteins prior to their delivery to their appropriate intracellular destinations. The GA consists of cis- (facing the ER), medial and trans cisternae (membrane stacks), and the trans-Golgi network (TGN).
All parts of the GA participate in the first role, whereas the TGN is particularly involved in the second and is very rich in vesicles.
