0\( \mathrm{Na}^{+}-\mathrm{K}^{+} \)pump is found in membranes of many cells, like nerve cells. It works against electrochemical gradient and involves an integral protein ATPase. For each molecule of ATP used
(A) three ions of \( \mathrm{Na}^{+} \)are pumped out and two \( \mathrm{K}^{+} \)are taken in
(B) three ions of \( \mathrm{Na}^{+} \)are taken in and two \( \mathrm{K}^{+} \)are pumped out
(C) two ions of \( \mathrm{Na}^{+} \)are thrown out and three \( \mathrm{K}^{+} \)are absorbed
(D) three ions of \( \mathrm{K}^{+} \)are absorbed and three \( \mathrm{Na}^{+} \)are pumped out
