To date, nothing in the oxymonad cell has been found that resembles a mitochondrion although it is clear that their ancestors must have had one. Priscila Peña-Diaz. Explanation: Simplify. intestinalis, T. Monocercomonoides are a genus of single-celled organisms that live as parasites in the guts of small animals. Monocercomonoides is a unique genus of eukaryotic microorganisms because of its complete lack of mitochondria or any mitochondrion-related organelles (MROs). Bacteria; Archea; Eukaryote; Endosymbiont It was commonly believed that all eukaryotic cells are required to have a mitochondrial organelle to survive, however, in 2016 with genome sequencing of an anaerobic eukaryotic microorganism, Monocercomonoides sp. Bacteria; Archea; Eukaryote; Endosymbiont Monocercomonoides comprises small oxymonads with cells less than 20 μm in length. These methods were used in five cell types from four mammalian species.

Monocercomonoides was a good candidate in this search because it sits among organisms with remnant mitochondria on the eukaryote family tree. It was proposed that an important prerequisite for such a radical evolutionary step was the acquisition of the SUF Fe–S cluster assembly pathway from prokaryotes, making the mitochondrial ISC pathway. The Monocercomonoides organism is an anaerobic protist that uses the process of fermentation to produce ATP which occurs in the cytoplasm.
