A physics student is asked to calculate the efficiency of ATP production in the human body, taking into account the thermodynamics of the metabolic pathway that converts glucose to ATP. Specifically, the student should determine the maximum efficiency of ATP production given the free energy change in this pathway, as well as the actual efficiency achieved by the body under typical physiological conditions.
