When a Eurokaryotic cell is placed in an aqueous (water) solution containing K+

Question

When a Eurokaryotic cell is placed in an aqueous (water) solution containing K+ and Na+ ions, one would expect that
A) nothing would happen B) the cell would swim away C) H20 would dissolve the membrane D) lipids would diffuse in and out of the cell through special membrane proteins E) K+ would be moved into the cell and Na+ would be moved outside of the cell membrane by special active transport proteins.

Explanation / Answer

E. K+ would be moved into the cell and Na+ would be moved outside of the cell membrane by special active transport proteins.

Because cell always need K+ for normal functioning of the cell.

Na - K ion pump actively transport 3 Na+ out and 2K+ in ,so the inner membrane becomes negatively charge compared to outer membrane.
