Which of the following is responsible for the repolarization of pacemaker cells? A) an increase in P_K B) an increase in P_Ca C) an increase in P_Na D) a decrease in P_Na E) a decrease in P_K

Question

Quizplus · Accepted Answer

Repolarization of pacemaker cells is primarily due to an increase in potassium permeability (P_K), which allows potassium ions to exit the cell, bringing the membrane potential back to a more negative value.
