Mitochondria

mitochondria /mi·to·chon·dria/ (mi?to-kon´dre-ah) sing. mitochon´drion   [Gr.] small spherical to rod-shaped cytoplasmic organelles, enclosed by two membranes separated by an intermembranous space; the inner membrane is infolded, forming a series of projections (cristae). Mitochondria are the principal sites of ATP synthesis; they contain enzymes of the tricarboxylic acid cycle and for fatty acid oxidation, oxidative phosphorylation, and many other biochemical pathways. They contain their own nucleic acids and ribosomes, replicate independently, and code for the synthesis of some of their own proteins.mitochon´drial
