Some living organisms are under considerable pressure tostreamline their genomes for the sake of more efficientoperation. As a result, the mitochondria of eukaryotic species have lost, to one degree or another, the overwhelmingmajority of their genes. During this process, several hundred mitochondrial genes were transferred to the nucleargenome. Yet mitochondria still retain a genome with thecapacity to produce several electron transport proteins.Review mitochondrial electron transport and suggest areason why these energy-generating organelles retained thegenes to produce this set of molecules.
