Proc. Nati. Acad. Sci. USA Vol. 87, pp. 6097-6101, August 1990 Biochemistry Some protists are aerobic and contain mitochondria and some are anaerobic, containing hydrogenosomes. Although some have no membrane-bounded organelles of energy metabolism (i.e. mitochondria used for cellular respiration), others contain hydrogenosomes, unusual organelles surrounded by two membranes (1, 2). These organelles are the site of oxidative decarboxylation of pyruvate with the formation of acetyl-CoA. This process is mediated by pyruvate:ferredoxin oxidoreductase and is coupled to anaerobic formation of H2 catalyzed by hydrogenase. This is a great reading for those that would like to know more about anaerobic protists!
