Answer:
What exactly are we supposed to help you with?
Explanation:
I am concerned.
The answer is generation and propagation of action potential.
Na+ channels are important for generation and propagation of action potential. In normal neurons, when neurons hit threshold and action potential is triggered, the Na+ channels open and Na+ ions enter the neuron. After the depolarization of membrane, Na+ channels inactivate. Thus, w<span>ithout Na+ channels, neurons would not be able to depolarize and consequently, the action potential would not be generated.
