Quizplus · Accepted Answer

When an ion crosses a membrane and binds to a protein, it can be through facilitated diffusion (if moving down its concentration gradient without the use of energy) or active transport (if moving against its concentration gradient with the use of energy). Both processes involve specific proteins to assist in the transport.
