Ion channel gates close the pores of some ion channels in response to
Evgen [1.6K]

Answer:

All of the above

Explanation:

The ions present in our body can move through voltage gated ions channels present in the cell. The ions are unequally distributed in the interior and exterior of the cell.

The ion gated channel may get open or close depending upon the presence of the different ions. These ions movement changes the electric potential of the cell. The ions movement results in the propagation of the nerve impulse and may cause the cell membrane stretching. The binding of the molecules to the ion channels may open or close the movement of particular ions.

Thus, the correct answer is option (d).
