Which of the following statements concerning the Na+-K+ pump is incorrect?
a. the phosphorylated conformation of the Na+-K+ pump has high affinity for K+ when exposed to the ICF. b. the Na+-K+ pump has ATPase activity. c. the Na+-K+ pump establishes Na+ and K+ concentration gradients across the plasma membrane; these gradients are critically important in the ability of nerve and muscle cells to generate electrical impulses essential to their functioning. d. the Na+-K+ pump helps regulate cell volume by controlling the concentration of solutes inside the cell to minimize osmotic effects that would induce swelling or shrinking of the cell. e. the ion concentration gradient established by the Na+-K+ pump drives cotransport carriers to move glucose against its concentration gradient across intestinal and kidney cells.
