If Na+ Channel is suddenly made or opened during resting potential it will lead to depolarisation, which in turn will open more Na+ channels. This will continue till the limit is reached and then the cycle to achieve the equilibrium starts. The Na+ channels close even though there is depolarisation and this state is called as inactivation.
This was explained by the neurobiologists, Hodgkin and Huxley in the 1950s.
What happens if a Na+ Channel is suddenly made during resting potential?
What is a resting potential? Is it positive or negative? The resting potential is mainly due to the main _____-charged large molecules stuck inside the neuron. The Na+/K+ pump pushes Na+ _____ of the cell and K+ ____ of the cell (in or out for each ion) Where is K+ concentrated, inside or outside of the neuron? Where is Na+ concentrated, inside or outside of the neuron? The action potential starts with an rise in membrane voltage. This is due...
Opening a sodium channel during the resting potential would cause sodium ions to move along an electrical gradient and along a concentration gradient. (T/F: Explain)

Q3 During the action potential, the cell depolarizes and goes back to the resting potential after a little hyperpolarization caused by O A The enter of Na+ through the Na+ channels OBThe enter of Na+ through the voltage-gated Na+ channels O cThe exit of K+ through the voltage-gated K+ channels O D The enter of Ca+ through the voltage-gated Ca+ channels
Question 4 2 pts During and action potential, sodium (Na+) rushes into the cell causing of the cell. Then sodium channels close and potassium (K+) rushes out of the cell, causing of the cell. However, the potassium overshoots and causes Question 5 2 pts During the refractory period, the pumps Na+ ions out of the cell and K+ions into the cell, re-establishing the resting membrane potential and concentration gradient.
