Opening of sodium gates typically leads to A repolarization of the plasma membrane back to resting membrane potential (RMP) B hyperpolarization of the plasma membrane, more negative than RMP. coepolarization of the plasma membrane, away from RMP. D. drifting of plasma membrane voltage toward a more negative value . E. all of the above 20. WebThe falling phase of the action potential is caused by the inactivation of the sodium channels and the opening of the potassium channels. After approximately 1 msec, the sodium channels inactivate. The channel becomes blocked, preventing ion flow. At the same time, the voltage-gated potassium channels open. WebIN A RESTING NERVE CELL MEMBRANE, all the sodium gates are closed and some of the potassium gates are open. AS A RESULT, sodium cannot diffuse through the membrane & largely remains outside the membrane. HOWEVER, some potassium ions are able to diffuse out. dutty winning
