A major determinant of the resting membrane potential necessary for the transmission of nerve impulses is the ratio between:
A) Intracellular and extracellular Na+
B) Intracellular and extracellular K+
C) Intracellular Na+ and extracellular K+
D) Intracellular K+ and extracellular Na+

Question

Quizplus · Accepted Answer

The ratio of K⁺ in the ICF to K⁺ in the ECF is the major determinant of the resting membrane potential,which is necessary for the transmission and conduction of nerve impulses,for the maintenance of normal cardiac rhythms,and for the skeletal and smooth muscle contraction.This is not true of the other options.
