Some organisms are under considerable strain to streamline their genomes for the sake of more efficient operation. As a result, the mitochondria of eukaryotic species have lost the overwhelming majority of their genes, of which several hundred were transferred to the nuclear genome. Yet mitochondria still retain a genome with the capacity to produce several electron transport proteins. Suggest a reason why these energy-generating organelles retained the genes to produce this set of molecules.
