Question

Depolarization is caused by the _________ of _________ ions while repolarization is caused by the _________ of _________ ions.

Select one:

a. efflux; K+; influx; Na+

b. efflux; Na+; influx; K+

c. influx; K+; efflux; Na+

d. influx; Na+; efflux; K+

Expert Solution

Step 1

CONCEPT:

Depolarization is the movement of a cell's membrane potential to a more positive value. This occurs due to the influx of Sodium ions that increases the concentration of positive charge inside the cell. Due to the increase in the concentration of positive charge in the cell, the cell potential becomes higher than the cells resting potential.

Repolarization is the decrease of membrane potential due to the efflux of potassium ions.
