(c) An experiment was set up to simulate the production of energy from ATP. In these experimental conditions it was found that an activity burning 500 kcal of energy requires 30 moles of ATP, determine the Gibbs free energy of ATP to ADP conversion in this case. Assuming that the usual estimation of Gibbs free energy is -11 kcal/mol what is the percentage error of your experimental set up? If total amount of body ATP is 0.1 moles how many cycles are required for this conversion? [5 marks)
