Opening of each of the following types of channels will contribute toward a graded potential except A)closed voltage-gated sodium channel. B)chemically gated acetylcholine receptor. C)sodium leak channel. D)mechanically gated sodium channel. E)inactivated voltage-gated sodium channel.

Question

Quizplus · Accepted Answer

Inactivated voltage-gated sodium channels do not contribute to graded potentials because they are in a state that prevents them from opening in response to a stimulus. This state follows the activation of the channel and precedes its return to the closed state, making it temporarily non-functional.
