Under physiological conditions, the hydrolysis of ATP to ADP releases ca 50 kJ mol^-1. Neurons derive their energy from concentration gradients created by pumping K⁺ across the cell membrane. If the nominal cell concentration of K⁺ is 50 mmol, how many moles of ATP must be hydrolyzed to create a 45 mV transmembrane potential?
