Because of the presence of both activation and inactivation gates, voltage-gated Na channels can be all of these.

  • Sodium voltage-gated channels can be either closed, open, or inactive.
  • Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
  • Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
  • Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
  • A greater amount of sodium will enter the cells as a result, initiating an action potential.
  • Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
  • The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."
  • Up until the membrane potential reaches its resting state, this occurs. The channels once more assume the "closed but capable of opening" conformation when resting values are attained.
