You have prepared lipid micelles that possess a leaky Na+ ion channel, and, for

(a) With equal amounts, there will be movement of Na+ to both sides of the micelle membrane but no net gain; therefore, no action potential will develop.
(b) If there is a higher concentration inside the membrane, Na+ ions will move out of the micelle until there is an equivalent amount on either side of the membrane; no action potential will develop.
(c) If there is a higher concentration outside of the membrane, Na+ ions will leak into the micelle until equivalent levels of Na+ ions are on both sides, again interfering with the development of an action potential.
