Under which conditions would the sodium-potassium pump likely be far less effective in creating a concentration gradient?
A) if dendrites were generally longer than axons
B) if the glia-to-neuron ratio were higher
C) if selective permeability of the membrane did not exist
D) if it were an active transport system that required energy

Question

The sodium-potassium pump relies on the selective permeability of the cell membrane to maintain a concentration gradient of sodium and potassium ions. If the membrane were not selectively permeable, ions could move freely in and out of the cell, undermining the pump's ability to create and maintain a gradient.
