In eukaryotic cells, mitochondria are the ATP-producing and oxygen respiring organelles. In malaria cells, mitochondria adapts morphologically and physiologically to the metabolic conditions of the host. Therefore, in the mosquito, gametocytes have aerobic metabolism and a mitochondria of typical appearance, whereas in the vertebrate, sporozoites and merozoites respond to a microaerophilic metabolism and the mitochondria have cristae inner membranes and a low density matrix. Consequently, its electron transport chain and susceptibility to mitochondrial-inhibitors differ substantially. The influence of metabolic inhibitors on pyrimidine de novo synthesis has been of particular interest in malaria drug development. The current review briefly describes adaptations of Plasmodium mitochondria during development, biochemical aspects of mitochondrial function and the potential of mitochondria as antimalarial drug targets.
