Mitochondria
Mitochondria are the major site of ATP production in the cell. They are formed by two unit membranes, the inner of which has folds, or cristae, that project into the interior of the mitochondrion. Mitochondria contain enzymes of the citric acid (Krebs) cycle, oxidative phosphorylation and the electron transport system. They also contain mitochondria DNA and are self-replicating. The number, shape and distribution of mitochondria vary with the type and cellular activity of the cell.
