- NERNST EQUATION: Concentration gradient ≈ electrical gradient: If that ion is K+: Vm = Vrest = VK+ =
- Ions are unequally distributed across the plasma membrane of all cells. This ion distribution creates an electrical potential difference across the membrane. What is the name given to this potential difference?
- Imagine you changed the concentration of K+ outside a neuron such that the resting membrane potential changed to -80 mV (from the normal resting value of -70 mV). What have you changed?
