Monday, September 11, 2017 BIO3P03: Membrane Potential: Ionic Equilibrium I (Lecture 2) Diffusion Potential • In the example from the ﬁrst lecture, a diffusion potential could be recorded by a voltmeter placed across the two compartments • This potential disappears after concentrations equalize across the barrier (i.e. once the gradient disappears) • Note: The potential tends to slow/‘retard’ the movement of Cl and facilitate movement of Na + • The diffusion potential disappears when [Na ] and [Cl ] are equal on both sides • When do you see a steady electric potential at equilibrium - If one of the two ions is extremely slow, making it essentially impermeable; Charge separation Equilibrium Potential: An Example • (Building on the example fr
