A) 3 ions of \[N{{a}^{+}}\] are pumped out and two \[{{K}^{+}}\] are taken in
B) 3 ions of \[N{{a}^{+}}\] are taken in and \[2{{K}^{+}}\] are pumped out
C) 2 ions of \[N{{a}^{+}}\] are thrown out \[3{{K}^{+}}\] are absorbed
D) 3 ions of \[{{K}^{+}}\] are absorbed and \[3N{{a}^{+}}\] are pumped out
Correct Answer: A
Solution :
Energy from ATP cause conformational change in the solute carrier complex. From energy of one ATP, 3 \[N{{a}^{+}}\] are pumped outside and two \[{{K}^{+}}\] are taken in. This process of expelling out \[N{{a}^{+}}\] ions and drawing in \[{{K}^{+}}\] ions against the concentration gradient and electrochemical gradient is called sodium - potassium exchange pump of the cell.You need to login to perform this action.
