<u><em>The answer is</em></u>: <u>Ion flows that generate an electric current through the membrane do not enter.</u>
<u></u>
Explanation:
Ionic channels are a type of transmembrane protein that allows specific ions to pass through the cell membrane.
<u>When the ion channels are closed</u>, without the possibility of conduction, they are impervious to the ions and do not conduct the electric current.
<u><em>The answer is</em></u>: <u>Ion flows that generate an electric current through the membrane do not enter.</u>
A gated channel is an example of facilitated diffusion. 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>
