B.permeability of a resting nerve cell membrane to A-
A)A is greater than B
B)B is greater than A
C)A and B are equal

Question

Quizplus · Accepted Answer

The resting membrane potential of a nerve cell is primarily determined by the permeability of the membrane to K⁺ ions. Therefore, the permeability of the resting nerve cell membrane to K⁺ (A) is greater than that to A- (B).
