If a Cell's Na⁺/ K⁺pump Worked in Reverse and Had

Question 23

Multiple Choice

If a cell's Na⁺/ K⁺pump worked in reverse and had more leak channels for Na⁺than for K⁺, what would the ion concentrations of the cell look like?

A) Intracellular Cl ^-would be increased, following Na⁺.
B) Intracellular anions would decrease in number.
C) Intracellular concentration of K⁺would still be higher than Na⁺because the body tries to maintain an extracellular concentration of Na⁺at 145 mM.
D) The cell would swell since water follows Na⁺.
E) Although the body tries to maintain an extracellular concentration of Na⁺at 145mM, the intracellular concentration of Na+ would still be higher.
