Closing of the voltage regulated gate of the Voltage gated Sodium channels

Your Answer
B

Sodium potassium ATPase pump

Correct Answer
C

Closing of the inactivation gate of Voltage gated Sodium channels

Your Answer
D

Synaptic neurotransmitter release


Solution

The correct option is B

Closing of the inactivation gate of Voltage gated Sodium channels


Closing of the inactivation gate of voltage gated Sodium channels. This gate of Voltage gated Sodium channel is not regulated, it closes a while after the channel is open and reopens again after a small period. The activity of this gate ensures that the action potential moves in the forward direction, opening voltage gated channels ahead of the signal and inactivating channels as the signal passes.
