Recall that the standard change in free energy for ATP synthesis is 30.5kJ/mol.
Based on this information, calculate the maximum number of ATP that could theoretically be made by ATP synthase using the
energy released by a pair of electrons moving through this electron transport pathway.
Round your answer to one decimal place.
