Place the events of the sodium potassium pump in order.
1)Carrier proteins bind to sodium
2)Potassium binds to the carrier which causes protein to lose the phosphate (dephosphorylation)
3)Loss of phosphate causes potassium to be moved into the cell.
4)ATP adds a phosphate (phosphorylates)to the protein.
5)Addition of the phosphate causes the protein to move sodium out of the cell.
6)Potassium can bind to the protein.
A)1,2,3,4,5,6
B)1,4,5,6,2,3
C)3,2,6,5,4,1
D)6,2,3,1,4,5

Question

Quizplus · Accepted Answer

The events of the sodium potassium pump occur in the following order:
1) Carrier proteins bind to sodium
2) ATP adds a phosphate (phosphorylates)to the protein.
3) Addition of the phosphate causes the protein to move sodium out of the cell.
4) Potassium can bind to the protein.
5) Potassium binds to the carrier which causes the protein to lose the phosphate (dephosphorylation)
6) Loss of phosphate causes potassium to be moved into the cell.
Choice B is the only option that follows this order.
