A gated channel protein is a transport protein that opens a "gate" allowing a molecule to pass through the membrane (usually molecules too big to enter the cell by passing through the membrane itself).<span> </span>Gated channels <span>have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).</span>
