29 Only proteins that are properly folded and assembled can leave the ER IncompleteER resident protein
30 Defect in Cl- transport CF (Cystic fibrosis)Defect in Cl- transportThis is not because the mutation inactivated the protein,But because the active protein is discarded before itreaches the plasma membrane.
31 Transport from the ER to the Golgi apparatus is mediated by vesicular tubular clusters.Heterotypic fusionHomotypic memb fusion is not restricted to form VTC.
32 The structure formed when ER-derived vesicles fuse with one another are called.
43 High specificendoglycosidaseCan distinguish betweenthese two type
44 Proteoglycans are assembled in the Golgi Apparatus O-linked glycosylationProteoglycans are secreted or anchored to plasma membrane
45 What is the purpose of N-glycosylation? 1. N-linked is prevalent in all eukaryotes, but absent in procaryotes.2. limited flexibility.3. Recognition4. Regulation of development5. Protective coat unit6. Cell-cell adhesion
