... • First, the action of the Na+/K+-ATPase pump sets up the concentration gradients for Na+ and K+ (Figure 6–13a). • Then there is a greater flux of K+ out of the cell than Na+ into the cell (Figure 6–13b). This is because in a resting membrane there are a greater number of open K+ channels than there ...
