B) the movement of one solute down its concentration gradient provides energy for transport of some other solute up its concentration gradient
C) a channel protein moves ions by facilitated diffusion
D) osmosis powers the movement of ions against their concentration gradient
E) sodium is directly transported in one direction, and potassium is indirectly transported in the same direction
