which molecules are processed by the rough endoplasmic reticulum
There are two types of endoplasmic reticulum (ER) - smooth and rough. The rough kind is covered with ribosomes on its outer surface and is involved in protein processing and sorting.The smooth ER is not associated with ribosomes and functions in lipid metabolism.See Figure 10.1.he rough endoplasmic reticulum (RER) which is continuous with the outer membrane of the nuclear envelope plays an important role in the sorting of proteins destined for various other locations in the cell, like the Golgi apparatus, the lysosomes and the plasma membrane.
