Question

Which of the following is NOT a characteristic of cardiacmembrane depolarization / polarization leading to generation of theaction potential?
a. The presence of a large amount of negative charges inside thecell creates a negative resting potential
b. There is a large amount of potassium inside the cells and a lotof sodium outside, creating a membrane potential, which causesopening of Na and K channels, beginning membranedepolarization
c. Along with Na, a large amount of Cl ions also enter the cells,further creating a negative membrane potential
d. In order to restore the resting potential, a Na/K ATPAse removes3 Na for every 2 K it takes in from the cytosol, leaving lesspositive charges inside the cell, returning to a negativepotential
