Molecules such as ammonia, nitrite, and H2S have more positive reduction potentials than the NAD(P) /NAD(P)H conjugate redox pair. How do chemolithotrophs transfer electrons to the less positive NAD from the more positive inorganic energy sources they utilize as fuels in order to gain reducing power
