Ions moving down a … WebbIon pumps are channels that use the ATP hydrolysis energy to transfer ions from one side of a membrane to the other against their electrochemical gradient (Harold, 1986; Laüger, 1991 ). Similar to passive channels, they are selective, i.e. a pump structure is only adapted to the passage of a particular ion.
