AP Biology Questions and Answers (Graded A) Resting membrane potential depends on which of the following(s)? I. Active transport II. Selective permeability III. Differential distribution of ions across the anxonal membrane All three. The resting potential depends on active transport (the Na+K+ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads to a differential distribution of ions across the axonal membrane Mitosis The division of the moth...
