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

Options

A. equal amount of RER and SER
B. more SER than RER
C. more than SER
D. more Golgi bodies and no ER.

Answer

C

Explanation

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.
