Web14 sep. 2024 · Ion 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. WebIon channels allow ions to passively flow down a concentration gradient across the membrane while ion pumps actively transport ions against a concentration gradient across the membrane. Thus, this is the key difference between ion …
