Question

Quizplus · Accepted Answer

Ion channels that are always open are known as leak channels. This is because they allow ions to move across the membrane at all times, without requiring any specific trigger or stimulus. Active channels, chemically-gated channels, voltage-gated channels, and mechanically-gated channels all require specific stimuli to open or close.
