3. Listed below are four redox couples. An organotroph uses compounds from two of these to carry out anaerobic respiration. A lithotroph uses compounds from two different couples to carry out aerobic respiration. Arrange these compounds into the redox towers below, showing which compounds would be the e' donors and acceptors for the two organisms, and how many moles of e would be transferred per mole of donor. Fe(OH)3/Fe +2 (E = -0.16V); SO4²/S (E = -0.25V); C₂H₂O2/C₁H6O2 (E = -0.20V); O₂/H₂O (E=0.82V) organotroph I lithotroph I Which organism would produce the most energy per mole of e donor? Show your work.

Expert Solution
Redox reactions

Oxidation and reduction reactions occur in synchrony within the cells. The Oxidation of one substrate is coupled with the reduction of another substrate. 

This phenomenon can be divided into 2 classes based on the nature of the electron donor.

  • Organotrophs: if the electron donor is organic substrate 
  • Lithotrophs: if the electron donor is inorganic substrate. 

The number of electrons transfered is calculated based on the nature of the substrate involved and Oxidation state of the species involved.
