Which gated ion channel is associated with membrane repolarization in neurons? A) Na⁺ channel B) K⁺ channel C) Ca²⁺ channel D) acetylcholine receptor ion channel E) both Na⁺ and Ca²⁺ channels

Question

Quizplus · Accepted Answer

The K⁺ channel, also known as the delayed rectifier potassium channel, is responsible for repolarizing the membrane of neurons by allowing potassium ions to exit the cell after an action potential. Na⁺ channels are responsible for depolarization and Ca²⁺ channels are primarily involved in calcium signaling. The acetylcholine receptor ion channel is involved in synaptic transmission.
