<P> Other processes substitute other compounds (such as arsenite) for water in the electron - supply role; for example some microbes use sunlight to oxidize arsenite to arsenate: The equation for this reaction is: </P> <Dl> <Dd> CO + (AsO) + photons → (AsO) + CO </Dd> <Dd> carbon dioxide + arsenite + light energy → arsenate + carbon monoxide (used to build other compounds in subsequent reactions) </Dd> </Dl> <Dd> CO + (AsO) + photons → (AsO) + CO </Dd> <Dd> carbon dioxide + arsenite + light energy → arsenate + carbon monoxide (used to build other compounds in subsequent reactions) </Dd>
