A  It extends the absolute refractory period

B  It makes action potentials shorter

C  It helps neurons repolarize more rapidly

D  It makes it more difficult for action potentials to fire

A  The S4 gate would be unable to close

B  The cell would get stuck in the repolarized state

C  Sodium channels would not open

D  Sodium channel activation would cause sodium efflux instead of influx

A  The electrical driving force keeps potassium from leaving the cell

B  Potassium leak channels must first be activated before potassium can enter or exit

C  There is no chemical gradient for potassium, so no driving force

D  The chemical driving force makes potassium enter the cell instead of leaving
