A)Activation gates of Na+ ion channels begin to close.
B)Inactivation gates of Na+ ion channels begin to open.
C)A positive feedback cycle develops in which depolarization causes activation gates of Na+ ion channels to open.
D)K+ ion channels begin to close.
E)Inactivation gates of Na+ ion channels begin to open and a positive feedback cycle develops in which depolarization causes activation gates of Na+ ion channels to open.

Question

Quizplus · Accepted Answer

When a local potential reaches threshold, it triggers the opening of activation gates of Na+ ion channels, leading to a positive feedback cycle of depolarization.
