Continuous with the outer portion of the nuclear pore, what membrane-bound structure functionsin the synthesis of secretory proteins, integral membrane proteins, or proteins bound for other organelles?
A) rough endoplasmic reticulum
B) lysosome
C) nucleolus
D) mitochondria
E) smooth endoplasmic

Rough endoplasmic reticulum functions in the synthesis of secretory proteins, integral membrane proteins, or proteins bound for other organelles. Rough endoplasmic reticulum is named for its rough appearance, which is due to the ribosomes attached to its outer (cytoplasmic) surface. The ribosomes on rough endoplasmic reticulum specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the endoplasmic reticulum for processing.
