A cell, which is very active in the synthesis and secretion of proteins, would be expected to have

A

equal amount of RER and SER

B

more SER than RER

C

more RER than SER

D

more Golgi bodies and no ER.

Text Solution

Verified by Experts

The correct Answer is:
C
The RER offers extensive surface on which protein synthesis can be conveniently carried on by the ribosomes. The proteins formed on ribosomes pass into the ER lumen where they are modified. Then the modified proteins move into the transitional area, where the ER buds off membranous sacs, the transport vesicles, carrying the proteins to the Golgi apparatus. Here, they are further processed and packaged into secretory vesicles for export by exocytosis at the plasma membrane.
