on the AP voltage curve that you drew above mark the following with letters and a pointer if needed
a treshold
b the point at which the Na+ channels first open(on the AP curve)
c the point at which the K+ channels first open (on the AP curve)
d the point at which the Na+ channels beguin to close (on the AP curve
E the point at which the K+ channels begin to close (on the AP curve)
(a) A will be the threshold level at which the Na+ mechanical gated channel opens.
(b) Depolarization, where only Na+ VGIC open
(c) Bothe the Na+ and K+ VGIC open (overshoot).
(d) Repolarization, Na+ VGIC closed and K+ VGIC open
(e) Hyperpolarization, K+ VGIC open
