Why are ion channels necessary to transport ions into or out of a cell?
ions are too large to diffuse through the membrane.
ions are charged particles and cannot diffuse through the hydrophobic interior of the membrane.
ions do not need ion channels to move through the membrane.
ions bind to carrier proteins in the bloodstream, which must be removed before transport into the cell.
