Hyperpolarization occurs because voltage-gated Blank______ channels stay open longer than required to reach resting membrane potential. Multiple choice question.sodiumpotassium

Voltage-gated sodium channels close and inactivation gates open at the end of Blank______.Multiple choice question.depolarizationrepolarization

If a neurotransmitter causes ligand-gated sodium channels to open, what occurs to the membrane?Multiple choice question.HyperpolarizationDepolarization

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.
