Depolarization of the Neuron Occurs When

Question

Depolarization of the neuron occurs when
A) the potassium gates open and potassium moves outside the cell.
B) the sodium-potassium pump moves sodium inside the cell.
C) sodium gates open and sodium moves inside the cell.
D) the sodium-potassium pump moves potassium inside the cell.
E) water moves to the outside of the cell and chloride ions follow.

Accepted Answer

Depolarization of the neuron occurs when sodium gates open and sodium moves inside the cell. This results in a change in the electrical charge across the cell membrane, making it less negative or more positive, which can trigger an action potential.
