During depolarization, which of the following statements about voltage-gated ion channels is TRUE
Wewaii [24]

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.
