4. Desulfovibrio africanus is an organotroph that carries out anaerobic respiration using two of the redox couples below to generate energy and reducing power. Thiobacillus denitrificans is a chemolithotroph that uses the waste product of Desulfovibrio's e transport system as a source of e, and also carries out anaerobic respiration using one more of the redox couples. Which organism would produce the most energy per mole of its e donor? Show your work. C3H403/C3H8O3(-0.28 V) 0₂/H₂O (+0.82) NO₂/N2 (+0.38 V) S2O32/H₂S (-0.18 V)
