Comments | Almost one-third of the energy requirement of a typical animal cell is consumed in fueling this pump. In electrically active nerve cells, which repeatedly gain small amounts of Na+ and lose small amounts of K+ during the propagation of nerve impulses, this number approaches two-thirds of the cell's energy requirement.
