The Endoplasmic Reticulum.


The endoplasmic reticulum (ER) within a cell is a network of rough or smooth tubular membranes that are involved with protein synthesis and transport.

The rough ER is studded with ribosomes which are the seat for protein synthesis. This ER is situated near the nucleus of the cell, is the site for the assembly and transport of proteins, and also assembles lipid components of the cell.

The smooth ER has no ribosomes on the surface, contains enzymes for lipid synthesis, is the site for the assembly of lipids, is also responsible for the breakdown and transport of waste products.

Both ERs have an internal tubular network and help to transport and export materials.
