Question
Hyperpolarization, or afterpotential, occurs becauseMultiple Choicemore sodium ions diffuse into the cell than potassium ions diffuse out of it.the extra efflux of potassium ions causes the membrane potential to become slightly more positive than the resting value.the increased potassium ion permeability lasts slightly longer than the time required to bring the membrane potential back to its resting level.potassium ions continue to diffuse out of the cell after the inactivation gates of the voltage-gated sodium ion channels begin to close.the inactivation gates of the voltage-gated sodium ion channels begin to open, and the diffusion of sodium ions decreases.
Solution
The correct answer is: "the increased potassium ion permeability lasts slightly longer than the time required to bring the membrane potential back to its resting level."
This is because hyperpolarization, or afterpotential, is a state where the membrane potential of a cell is more negative than its normal resting potential. This occurs due to the fact that the potassium channels remain open for a slightly longer duration than the sodium channels during an action potential. As a result, more potassium ions leave the cell than sodium ions entering it, making the inside of the cell more negative than the resting potential.
