Final answer:
During resting potential, voltage-gated sodium channels are closed, and potassium channels remain open at 90% conductance. The movement of potassium ions out of the cell helps maintain the negative charge inside the cell. The constant action of the sodium-potassium pump restores the resting potential.
Step-by-step explanation:
During the resting potential, there are changes in ion channels and ion movement in the cell membrane. At rest, voltage-gated sodium channels are closed, while potassium channels remain open at 90% conductance. This allows potassium ions to flow out of the cell, maintaining the negative charge inside the cell relative to the outside. The sodium-potassium pump constantly transports ions to restore the resting state of the membrane potential (-70 mV).
