When sodium ion channels open, what happens to the cell's membrane potential? depolarization repolarization the cell maintains its resting membrane potential hyperpolarization
Added by Natasha A.
Step 1
- At rest, the cell's membrane potential is negative, typically around -70 mV. This is due to the selective permeability of the cell membrane, which allows potassium ions (K+) to leak out of the cell more easily than sodium ions (Na+) to enter. Show more…

In a neuron, the opening of sodium gates typically leads to depolarization of the plasma membrane.
Adi S.
During an action potential, depolarization occurs because: - Voltage-regulated gates for sodium ions in the cell membrane open, and sodium flows into the cell. - Voltage-regulated gates for potassium ions in the cell membrane open, and potassium leaves the cell. - The sodium-potassium pump returns sodium to the outside of the cell and potassium to the inside.

In a neuron, the opening of sodium gates typically leads to: - depolarization of the plasma membrane - plasma membrane voltage returning to the resting membrane potential
