Kinetic evaluation of the Na-K pump reaction mechanism. When a Hill equation was fitted to the data, it was found that KNac was higher at the high external K concentration, but n was the same at both K concentrations. The source of energy for this transport process was hydrolysis of ATP. An equation for membrane voltage is derived that takes into account the electrogenicity of the NaK pump and is valid dynamically, as well as in.
