Many aerobic bacteria (both facultative and obligate) possess a number of those biochemical features of mitochondria which are concerned with energy metabolism. However, only restricted number, notably Paracoccus denitrificans and Rhodopseudomonas spheroides, have the majority of these features. The theory of endosymbiosis proposes that a primitive eukaryote took up bacteria to yield mitochondria. The present-day Paracoccus then resembles the ancestral bacterium in many respects the primitive amoeba, Pelomyxa palustris, which lacks mitochondria but contains a permanent population of unique symbiotic bacteria, has many of the characteristics of a present-day transitional form. The evolution of mitochondria from endosymbiotic bacteria would involve their integration with the host cell both biochemically and structurally: a number of the intermediate steps are discussed. Attention is drawn to the existence in some ciliates of hydrogenosomes, which function as anaerobic mitochondria.
