Monocercomonoides Travis has a small oval to pyriform body (5–15 μm in length) and four flagella arranged in two pairs, with one which is recurrent and attached to the body (Fig. Another implication of missing an MRO, in many ways more puzzling, is the absence of a mitochondrial Fe-S biosynthesis pathway (ISC). They lack mitochondria, but other evidence shows them to be most closely related to members of the excavates. 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. . This final stage of the mitochondrial evolutionary pathway may serve as a model to explain events at their very beginning. 1A) [28, 29,. mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP).
