The concentrations of ATP, ADP, and AMP in a particular rat hepatocyte cell are 3.38 mM, 1.32 mM, and 0.29 mM, respectively. Using the information you used in problem 9, calculate the Gibbs Free Energy (ΔG) for the reaction
ATP + AMP ⇌ 2 ADP
under these conditions at 37°C. Give your answer in kJ/mol to one decimal (tenths) without units.
