n increase in the membrane permeability to potassium ions results in Blank______.Multiple choice question.hyperpolarizationdepolarization

Which of the following changes would hyperpolarize a cell, that is, make the resting membrane potential more negative?  none of the choices are correct   decrease the temperature   increase extracellular levels of potassium   decrease the permeability of cells to potassium Correct Answer  decrease extracellular levels of potassium

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

During a resting membrane potential, the concentration of potassium inside the cell is Blank______ the concentration of sodium inside the cell.Multiple choice question.the same asdifferent from

n repolarization, the membrane potential Blank______.Multiple choice question.returns to a hyperpolarized levelreaches thresholdreturns to resting membrane potentia

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.potassium ions continue to diffuse out of the cell after the inactivation gates of the voltage-gated sodium ion channels begin to close.the increased potassium ion permeability lasts slightly longer than the time required to bring the membrane potential back to its resting level.
