How does the structure of the endoplasmic reticulum serve its purpose?
A) Its flattened sacs allow it to store protein.
B) Its membranous canals and curving sacs keep the plasma membrane from collapsing.
C) Its network of canals allows proteins to move toward the Golgi apparatus.
D) Its membranous vesicles contain various enzymes.

Question

Quizplus · Accepted Answer

The endoplasmic reticulum's network of canals allows proteins to move toward the Golgi apparatus, where they can be modified, sorted, and transported to their final destinations. This is essential for protein synthesis and secretion. The other choices are incorrect because the endoplasmic reticulum does not primarily store protein (A), prevent the plasma membrane from collapsing (B), or contain various enzymes in its vesicles (D).
