The '''Endoplasmic reticuluman''' is an [[organelle]] composed of an extensive network of folded [[membrane|membranes]] which perform several tasks within a [[cell]], such as [[ribosome]] transportation and storage.<ref>Wile, Dr. Jay L.

The '''Endoplasmic reticuluman''' is an [[organelle]] composed of an extensive network of folded [[membrane|membranes]] which perform several tasks within a [[cell]].  Notably, processing of secretory proteins, steroid synthesis, and calcium storage.<ref>Wile, Dr. Jay L.

The organelle can be divided into two main sections:

The organelle can be divided into two main sections:

* '''Rough endoplasmic reticulum''' - so called because of the ribosomes on its surface, this is where protein synthesis occurs

* '''Rough endoplasmic reticulum''' - so called because of the ribosomes on its surface, this is where synthesis of secreted proteins occurs

* '''Smooth endoplasmic reticulum''' - does not have ribosomes, site of lipid metabolism and drug detoxification

* '''Smooth endoplasmic reticulum''' - does not have ribosomes, major site of lipid metabolism and post-translational protein modifications.
