Calculate free energy (ΔG) for transporting 3 moles of Ca2+ from inside to outside of a typical cell. (Using Ca2+ = 1.5mM for outside the cell; [Ca2+] = 0.1 µM for inside the cell; T = 298k; R = 1.987x10^3 kcal/mol/deg; membrane potential (ΔV) = -50 mV (inside negative); Faraday constant = 23.1 kcal/V/mol).
