Answer:
rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)
Explanation:
rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)
The proteins move from the rough ER to the transport vesicle and cisternae of the Golgi apparatus and, further with secretory or transport vesicle, are released from the cell surface (exocytosis). Thus, option A is correct.
The protein pathway (secretory) is the mechanism of the transportation of the newly synthesized proteins by ribosomes that are transported out of the cell. The proteins are first present on the ribosomes of the ER.
For post-translational modification proteins from rough ER are transported to the Golgi apparatus. From the Golgi vesicles and cisternae, the proteins are packed in the secretory or transport vesicles to the cell surface where they are thrown out of the cell by exocytosis.
Therefore, the pathway of the newly synthesized protein is rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis).
