An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is a membrane protein with an aqueous pore, meaning it allows soluble materials to travel across the ...

The transport of ions is essential to maintain electrophysiological balance on either side of the membrane, called osmotic balance, which is needed for signals to be transduced from their chemical ...

Current connection: Schematic diagram of the ion-wire-ion system. Two ions are trapped at either end of an electrically floating wire that is at room temperature. (Courtesy: Da An) Scientists at the ...
