Neurоn Actiоn Pоtentiаl - Pаrt 2 Tаke a look again at the graph of an action potential on the membrane of a neuron (given below). Describe what is happening in the voltage-gated sodium channels and the voltage-gated potassium channels during the point in time on your graph 1) when threshold is reached, 2) during the depolarization phase, 3) during the repolarization phase, and 4) during the hyperpolarization phase. What are the two ion channels doing at each of these 4 points/phases? Tip: remember that sodium channels have two gates and three states, whereas potassium channels have one gate and two states.
