Mitochondria are essential for normal functioning of almost all cells, since they are the main production sites of the energy-carrying molecule adenosine triphosphate (ATP). In addition, mitochondria are the key sites of biosynthesis of various proteins, lipids, nucleotides and signaling molecules. Interestingly, mitochondria appear to descend from bacteria that were incorporated into cells and put into their service early during biological evolution.
