Which of the following provides the best description of depolarization?
I am not able to see the options. But here is the definition of depolarization:
During depolarization, the charge within the cell rapidly shifts from negative to positive. For this rapid change to take place within the interior of the cell, several events must occur along the plasma membrane of the cell as well. While the sodium potassium pump continues to work, the voltage gated ion channels that had been closed while the cell was at resting potential have been opened by an electrical stimulus. As the sodium rushes back into the cell the positive sodium ions raise the charge inside of the cell from negative to positive. Once the interior of the cell becomes positively charged, depolarization of the cell is complete.
