RE: What do I need a ICC-MC number for? I&#39;m starting a small transportation business with a partner, we have a US DOT # already, Do I also need a ICC-MC # and what is it for? We are transporting interstate and I want to be in compliance. We are driving dually trucks with 53&#39; step deck trailers.
Voltage-gated ion channel Voltage-gated ion channels are a class of transmembrane ion channels that are activated by changes in electrical potential difference near the channel; these types of ion channels are especially critical in neurons, but are common in many types of cells.
Voltage-gated K+ channel (called the delayed rectifying K+ channel). This channel has only two states, closed and open. The channel is opened with a strong depolarization, the type you would normally get in an action potential. This channel works to bring the membrane back towards the Nernst potential for K+ i.e. hyperpolarize the membrane. The channel will close when the membrane becomes hyperpolarized or repolarized.
