Concept #1: Sodium-Potassium Ion Pump

Concept #2: Sodium-Potassium Ion Pump: a P-Type ATPase

Practice: The critical function of the sodium-potassium pump is to move:

Practice: Which of the following statements about the mechanism of the sodium-potassium ATPase is FALSE?

Practice: Which of the following shows the correct order of steps for the mechanism of the sodium-potassium ATPase?

I. 2 K+ Ions bind.
II. Phosphorylation of an Asp residue.
III. Conformational change releasing 3 Na+ ions outside the cell.
IV. 3 Na+ ions bind.
V. Release of the phosphate group.
VI. Conformational change releasing 2 K+ ions inside the cell.
