During an action potential, depolarization occurs as a result of

K ions diffusing to the outside of the cell membrane
K ions diffusing to the inside of the cell membrane
Na ions diffusing to the outside of the cell membrane
Na ions diffusing to the inside of the cell membrane
Na and K ions not diffusing

Respuesta :

Answer:Action potentials result from the depolarization of the cell membrane (the sarcolemma), which opens voltage-sensitive sodium channels; these become inactivated and the membrane is repolarized through the outward current of potassium ions.
