The repolarizing phase of the action potential
A) means that the inside of the cell is becoming more positive.
B) is due to the movement of sodium (Na⁺)into the cell.
C) is due to the movement of potassium (K⁺)out of the cell.
D) is due to the Na⁺/ K⁺ pump located in the membrane.

Question

Quizplus · Accepted Answer

The repolarizing phase of the action potential is due to the efflux of K⁺.As K⁺ diffuses out,positive charge leaves the cell,thereby making the interior of the cell negative.
