In most cells the smooth endoplasmic reticulum (abbreviated SER) is scarce. Instead there are areas where the ER is partly smooth and partly rough, this area is called the transitional ER. The transitional ER gets its name because it contains ER exit sites.

WebThere are two types of ER: rough ER and smooth ER. The outer side (facing the cytosol) of the rough ER is studded with ribosomes. Under the electron microscope, the dense granular ribosomes gave the name of “rough” ER. Rough ER stays closer to the nucleus and coordinates protein synthesis. Smooth ER lacks ribosomes. WebA.
