Question

contrast
list two differences between the smooth and rough er.

Explanation:

The rough endoplasmic reticulum (ER) has ribosomes attached to its surface, which are absent on the smooth ER. The rough ER is mainly involved in protein synthesis and modification, while the smooth ER is involved in lipid synthesis, detoxification, and calcium ion storage.

Answer:

1. Structure: Rough ER has ribosomes on its surface; smooth ER does not.
2. Function: Rough ER is for protein - related processes; smooth ER is for lipid synthesis, detoxification, etc.
