Biological Importance

Iron is required for nutrition by all organisms, prokaryotic and eukaryotic alike, with a small group of homolactic fermenting bacteria being the only known exception. It is needed in enzymatic processes during aerobic or anaerobic respiration that involve the transfer of electrons to a terminal acceptor. Photosynthesizers require Fe for ferrodoxin, which is part of the photosynthetic pathway. Ferrous iron (Fe2+) can be used as a major energy source by some bacteria, while ferric iron (Fe3+) can be used as a terminal electron acceptor under different conditions by the same or other bacteria. Fe2+ may have served as an important reductant during the evolution of photosynthesis as a scavenger of the toxic oxygen produced
