On outer side Na+ concentration is less ,on inner side k + concentration is less
On outer side a plasma membrane + ve charge and inner side is -ve charge
Electrically it is neutral in resting stage.

Which option indicates correct chronology of the changes occuring during transmission of nerve impulse ?

Nerve fibre - depolarization - action potential - repolarization - activation of Nad⁺d and Kd⁺d pump
Nerve fibre - depolarization - action potential - activation of Nad⁺d and Kd⁺d pump - repolarization
Nerve fiber - depolarization - repolarization - action potential - activation of Nad⁺d and Kd⁺d pump
Nerve fiber - Activation of Nad⁺d and Kd⁺d pump - depolarization - repolarization -

What is responsible for the opening and closing of ion-channel ?

Electrical changes & Chemical Changes
