Answer
A chanel will always assist the movement of K+ and Na+ ions by providing a open pore across the membrane. Threfore, the movement of Na+ and K+ becomes easier. While, the movement of K+ and Na+ ions through the pumps requires a carrier. These carriers requires ATP for doing their work. Therefore, movement becomes ATP dependent. Hence, movement of Na+ and K+ slow down in the pumps.
