Question

A gated channel in a cell membrane allows

Answer 1

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). Gated channels have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).

Answer 2

The answer is: Ion flows that generate an electric current through the membrane do not enter.

Step-by-step explanation:

Ionic channels are a type of transmembrane protein that allows specific ions to pass through the cell membrane.

When the ion channels are closed, without the possibility of conduction, they are impervious to the ions and do not conduct the electric current.

The answer is: Ion flows that generate an electric current through the membrane do not enter.
