Eukaryotic cells have evolved an endomembrane system, containing membrane-bound organelles involved in transport. These include vesicles, the endoplasmic reticulum, and the Golgi apparatus. The smooth endoplasmic reticulum plays a role in lipid biosynthesis, carbohydrate metabolism, and detoxification of toxic compounds.
Theory. ER is a network of membranous sacs that form interconnected tubules, vesicles and cisternae. In 1945, Ernest Fullam, Keith Porter and Albert Claude were observed the endoplasmic reticulum. The ER membrane is a continuation of the outer nuclear membrane.The eukaryotic cells have ER.he endoplasmic reticulum is a highly versatile organelle involved in synthesis and transport of proteins, glycoproteins, and lipoproteins; synthesis of cholesterol, steroids, phospholipids, and triglycerides; it participates in degradation of glycogen, and in the metabolism of xenobiotics.
