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.
Title: The Endosymbiotic Theory Revisited: the Origins and Evolution of Mitochondria in Living Eukaryotes Introduction-One of the features that distinguish a eukaryotic cell from a prokaryotic cell, besides the presence of a âtrue nucleusâ encasing its DNA, is the presence of interior organelles such as the mitochondria. The theory is that there was a time when the ancestors of modern eukaryotes did not have mitochondria but later obtained them from an outside source, which had found its way into the host cell. This is known as the serial endosymbiotic theory (SET), which was proposed by Lynn Margulis in the 1970s and in later reports (Margulis, 1996). The endosymbiosis is usually described as the endocytosis or
