1. The problem statement, all variables and given/known data I have been asked to explain what Endoplasmic Reticulum Smooth and Rough is and what the functions are of it. 2. Relevant equations N/A 3. The attempt at a solution There are two recognized parts of the ER - Rough and Smooth - with the rough part of the ER synthesizing proteins with ribosomes attached to it with the smooth ER having the function for synthesizing of lipids. ---------- Is this even right? I basically need to just explain what it is breifly and what the functions are of it. Thanks.
