Microbial Metabolism

1.a) A chemolithotrophic reaction that’s based on the energy that hasn’t been accessible for ATP synthase in a A chemoorganoheterotrophic reaction with iron as the electron acceptor: What are the energy source, electron donor, electron acceptor, and coal source in this reaction?

1.b) A chemolithotrophic reaction that utilizes a potential difference of 850 mV. What are the energy source, electron donor, electron acceptor, and coal source in this reaction? Explain how and why you deduce that the potential difference for the reaction you propose is 850 mV.
