Hydrogenosome

Activity in a Spironucleus salmonicida hydrogenosome: pyruvate (PYR) is turned into carbon dioxide (CO2) and acetate while producing molecular hydrogen (H2) and converting ADP into ATP

A hydrogenosome is a membrane-enclosed organelle found in some anaerobic ciliates, flagellates, and fungi. Hydrogenosomes are highly variable organelles that have presumably evolved from protomitochondria to produce molecular hydrogen and ATP in anaerobic conditions.[1]

Hydrogenosomes were discovered in 1973 by D. G. Lindmark and M. Müller. Because hydrogenosomes hold evolutionary lineage significance for organisms living in anaerobic or oxygen-stressed environments, many research institutions have since documented their findings on how the organelle differs in various sources.[2]
