Introduction: Mitochondria

Description of Mitochondria

Mitochondria: self-replicating organelles found in cytoplasm bound by two membranes, the inner one folded into the interior as a series of projections; they are the principal sites of energy generation resulting from the oxidation of food, and contain the enzymes of the Krebs and fatty acid cycles and the respiratory pathway; they contain DNA and RNA for independent replication.

Mitochondria: Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed).
