For instance, one Voltage gated ion channel that We're Going To focus on in detail is the Sodium Voltage gated ion channel. And this voltage gate ion channel exists across the axon membrane of neurons, and it plays a very important part in actually generating and propagating action potentials along the exxon of that neuron. So this is our sodium voltage gated ion channel. And let's suppose when we're at the resting membrane potential. So a voltage difference of about negative 60 millivolts. This channel is closed.
