WebA voltage-gated channel is a channel that responds to changes in the electrical properties of the membrane in which it is embedded. Normally, the inner portion of the membrane is at a negative voltage. When that voltage becomes less negative, the channel begins to allow ions to cross the membrane ( [link] ). Voltage-Gated Channels WebA) ion-gated channels B) voltage-gated channels i. voltage gated K+ channels open when a particular membrane potential is reached, they are closed at resting membrane potential. Depolarization refers to a change in charge in the interior of the cell, which causes a change in voltage. C) stimulation-gated channels D) potential-gated channels

WebAnswer 10 When chemically gated Cl- channels open in the membrane of a resting nerve cell, Cl- ions leave the cell. Therefore, the correct option is b: Cl- ions leave the cell. . This results in hyper polarization, which means the cell becomes more negative than its resting potential, and makes it more difficult for the cell to generate an action potential.
