An ATP-coupled transporter is used to import 1 phosphate from the extracellular environment. Intracellular phosphate exists at 65mM, while it is 2mM outside.Assume a free energy change of ATP hydrolysis of -42.7 kJ/mol. What is the net free energy change of the coupled reaction? Assume a membrane potential of 70mV.
