Questions and Answers

What is the function of the rough endoplasmic reticulum?

Involved in protein synthesis and transport of proteins.

How does the smooth endoplasmic reticulum differ from the rough endoplasmic reticulum?

No ribosomes attached to its membrane, synthesizes substances such as fats and steroids, and detoxifies harmful substances.

What is the role of the Golgi body in the cell?

Chemically modifies substances made by the endoplasmic reticulum, stores and packages these substances in vesicles for secretion out of the cell.

How are substances made by the Endoplasmic Reticulum moved out of the cell?

<p>Vesicles transport substances within the cell, small vesicles containing substances made by the endoplasmic reticulum are pinched off from the endoplasmic reticulum, then fuse with the Golgi body and release their contents into the Golgi body, modified substances are carried in secretory vesicles to the cell membrane and released out of the cell.</p> Signup and view all the answers
