Define depolarization, and describe the events that follow it
A) Depolarization is the when the inside of the cell becomes negative due to sodium ions rushing out. After depolarization, repolarization occurs when potassium ions rush into the cell causing the inside of the cell to become positive again.
B) Depolarization is the when the inside of the cell becomes positive due to sodium ions rushing in. After depolarization, repolarization occurs when potassium ions rush out of the cell causing the inside of the cell to become negative again.
C) Depolarization is the when the inside of the cell becomes negative due to potassium ions rushing out. After depolarization, repolarization occurs when sodium ions rush into the cell causing the inside of the cell to become positive again.
D) Depolarization is the when the inside of the cell becomes positive due to potassium ions rushing in. After depolarization, repolarization occurs when sodium ions rush out of the cell causing the inside of the cell to become negative again.
E) Depolarization is when the inside of the cell becomes neutral due to an equal amount of sodium ions entering the cell and potassium ions leaving the cell.
