D)by closing spontaneously soon after opening

Question

Quizplus · Accepted Answer

Most voltage-gated channels are inactivated by closing spontaneously soon after opening. This occurs through a process called "fast inactivation", where a part of the channel called the inactivation gate swings shut shortly after the activation gate opens. This prevents the channel from staying open for an extended period of time, and helps to regulate ion flow across the membrane.
