AP Biology Practice Question 1
The resting membrane potential depends on which of the following?
I. Active transport
II. Selective permeability
III. Differential distribution of ions across the axonal membrane
Correct Answer: D
D 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.
