Please complete the following statement most accurately. The resting membrane potential is ALWAYS…

1. a)  equal to potassium’s equilibrium potential, EK.
2. b)  at a potential where the all currents through the membrane sum to zero.
3. c)  equal to that determined by the Goldman-Hodgkin-Katz equation for the three ions, Na+, K+, and Cl-.
4. d)  at a point where the sodium current into the cell equals the potassium current out of the cell.
5. e)  the voltage half way between ENa and EK.
