If K+ can exit the cell through leak channels, why don't they flow out until there are equal concentrations on both sides of the membrane?
A. K+ can act as an enzymatic cofactor, and most K+ ions are bound to cellular enzymes.
B. The leak channels allow a very slow leak that cannot keep pace with active import of K+ ions.
C. Chelator molecules trap K+ on the inside of the membrane.
D. The negative electrical potential inside the cell creates a force that holds the K+ ions in.
