The polarity that exists across a cardiac cell membrane is maintained by an active transport process known as
A)the cardiac cycle.
B)fibrillation.
C)sodium-potassium ion pump.
D)pinocytosis.

Question

Quizplus · Accepted Answer

All cardiac cell membranes are positively charged on their outer surfaces owing to the relative distribution of cations.This resting membrane potential is maintained by an active transport mechanism called the sodium-potassium ion pump.
