Web21 okt. 2011 · Ion channels set up the resting membrane potentials of all cells. Since the flow of ions moves charge and constitutes an electric current, channel opening and closing underlie all electrical signaling of electrically excitable cells such as nerve and muscle. There are two distinctive features of ion channels that differentiate them from other types of ion transporter proteins: 1. The rate of ion transport through the channel is very high (often 10 ions per second or greater). 2. Ions pass through channels down their electrochemical gradient, which is a function of ion concentration and membrane potential, "downhill", without the input (or help) of metabolic energ…
