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.
Mitochondria and chloroplasts â the organelles responsible for energy conversion in eukaryotes â are thought to be examples of this sort of ancient mutualism. Numerous lines of evidence support the hypothesis that these organelles are the descendants of endosymbiotic (literally, âliving together, withinâ) bacteria.
