You Have Prepared Lipid Micelles That Possess a Leaky Na

Essay

You have prepared lipid micelles that possess a leaky Na+ ion channel,and,for purposes of experimentation,the cytosolic sides of the channels are facing outward. Predict what will happen with the Na⁺ ion movement and the probable impact on the development of an action potential across the micelle membrane if (a)there were an equivalent amounts of Na⁺ ions on both sides of the membrane,(b)a greater Na⁺ ion concentration inside the micelle,and (c)a greater concentration of Na⁺ ions outside the micelle.
