Unformatted text preview: y similar. In fact you can combine the two and derive the magnitude of the chemical force as a function of the equilibrium potential (Eion). You do this by rearranging equation 1 and solving for RT/F *ln([Iout]/[Iin]) Eq. 2c Fchemical = RT/F *ln([Ion]out/[Ion]in = z * Eion The equation for the magnitude of the electrical force driving an ion through the CM is Eq. 3 Felectrical = z*V The equation for the net force driving an ion through the CM is Eq. 4a Fnet = Fchemical + Felectrical
This is vector notation remembering to take into account the direction of the forces (arrows in lecture) You can subst...
