An ion channel is a cell membrane channel that is selectively permeable to specific ions, such as calcium, potassium, and sodium. There are different types of ion channels such as a potassium leak channel, which creates a negative charge inside of the cell, but can an ion channel be gated since it selects certain ions? And if yes, then how and what ways can it be gated?
Voltage gated ion channels have been observed, where, there would be presence of transmembrane proteins that would be resulting in these ion channels. There would be an alteration of the potential of the membrane, which would be altering the confirmation of the protein channels, Rhys regulating the opening as well as closing of channels. Since, the cell membranes would be impermeable to one, diffusion would be taking place through protein channels. These channels would be specific to the ions. The closing and opening of the channels would be regulated by the change in ion concentration l these have been observed in case of potassium channels, sodium channels, chloride as well as calcium.
