2) involved in protein synthesis

3) involve in lipid synthesis

4) contains molecular chaperones in lumen

5) bound with ribosomes

6) involved in toxin or drug metabolism

7) large systemot internnected tubules,vesicles, and sacs

8) "Packages" enzymes in vesicles for secretion.

Explanation / Answer
