Sequence of vesicle transport is:: (A) ER - Trans - Cis - Lysosomes, (B) ER - Cis - Trans - Cell membrane, (C) ER- Lysosomes - Trans - Cis, (D) Cis - ER - Trans - Cell membrane
Answer is B. Ans. (b) ER - Cis - Trans - Cell membrane(Ref: Ganong, 25th ed/p.44)Proteins are synthesized in rough endoplasmic reticulum - enters Golgi through its cis end - processed inside golgi - packed in secretory vesicles - leaves out of golgi through its trans end - ultimately released out of the cell by fusion of vesicles with cell membrane
