Endoplasmic Reticulum Non-granular

The endoplasmic reticulum (ER) plays an important role in the formation and exchange of molecules of metabolites and fatty acids, as well as the implementation of respiration processes, energy transfer and transport of substances between cells. The ER combines the cell transport system and the system of synthesis and breakdown of substances. Thanks to membranes, endoplasmic reticulum is present in all eukaryan cells
