Ion channels that switch open and close as the potential difference across the cell membrane changes...
Ion channels that switch open and close as the potential difference across the cell membrane changes are an essential component of the cell membrane. Most such channels contain a molecular ion with a significant electrical charge at their core. Suppose a protein contains a molecular ion with a charge of -12e and that this protein is embedded in a cell membrane that has a thickness of 9 nm. What are the magnitude and direction of electric force on the ion...
