BIO 315 Exam I (F2014)
... rush into the cell until the membrane undergoes a full depolarization to +50 mV. This change in membrane potential then stimulates voltage-gated K+ channels to open, allowing K+ to now flow out of the cell. This brings about a repolarization of the membrane to near its resting membrane potential. 2) ...
