If stimulus occurs that strong enough reach the threshold level action potential. During repolarization more sodium can enter the cell. But many other types ion channels not have inactivation gate. An action potential triggered graded potential that causes the membrane depolarize until reaches the threshold for activation of. Here the inactivation gate closed thouh the activation gate still open above the threshold potential. Voltagegated potassium channels activated during action. Na activation gate closes action potential complete. For example the inactivation gate should not able close unless the activation gate open and the. Activation gate and slowacting inactivation gate.

Answer action potentials depend sodium currents which inactivate when subjected continuous depolarization. Action potentials are triggered when enough depolarization accumulates bring the membrane potential threshold. During action potential sodium channels first activate. A nerve impulse rapid lasts. A positive feedback loop sodium entry closed and thus action potential fired. If excitable cell present hyperkalemic state the rmp moves near the threshold potential for longer time may lead the closure inactivation gates the channels.

Quickly memorize the terms. Inactivation gate activation gate rapid. These are the cells with the capability generate action potentials. The activation gate will close once the membrane potential becomes hyperpolarized below its threshold.Thus because channels are inactivated during this time additional depolarizing stimuli not lead new action potentials.
