WebThe realization that ion channels are involved in many cellular processes, including the secretion of hormones, the transfer of substances across epithelia, and the regulation of cell volume, has come with the development of novel biophysical methods. WebChannels Channel proteins span the membrane and make hydrophilic tunnels across it, allowing their target molecules to pass through by diffusion. Channels are very selective and will accept only one type of molecule (or a few closely related molecules) for transport. Here, the cell can't import glucose for free using diffusion, because the natural …
