이온 채널과 막의 전기적 성질(ion channels 와 membrane의 electrical properties)

목차

Ion channels ion-selective and fluctuate between open and closed states
The membrane potential in animal cells depends mainly on K⁺ leak channels and the K⁺ gradient across the plasma membrane
The resting potential decays only slowly when the Na⁺- K⁺ pump is stopped
The three-dimensional structure of a bacterial K⁺ channel shows how an ion channel can work
The function of a nerve cell depends on its elongated structure
