<span>The
answer is facilitated diffusion. It requires no energy because the ions are
traveling down the concentration
gradient. Facilitated diffusion is important
for the regulation of ions in a cell. It also enables
ions to pass across the hydrophobic layer of the cell membrane composed
of phospholipids.</span>
