How does the sodium-potassium pump contribute to the net negative charge of the interior of the cell?
Added by Frederick E.
Step 1
Step 1: The sodium-potassium pump actively transports three sodium ions out of the cell and two potassium ions into the cell, using ATP as an energy source. Show more…

How does the sodium-potassium pump contribute to the net negative charge of the interior of the cell? a. The sodium-potassium pump forces out three (positive) $\mathrm{Na}^{+}$ ions for every two (positive) $\mathrm{K}^{+}$ ions it pumps in, thus the cell loses a net positive charge of one at every cycle of the pump. b. The sodium-potassium pump expels three ions $\mathrm{K}^{+}$ for every two $\mathrm{Na}^{+}$ inside the cells, creating a net positive charge outside the cell and a net negative charge inside the cell. c. The sodium-potassium pump helps the development of negative charge inside the cell by making the membrane more permeable to negatively charged proteins. d. The sodium-potassium pump helps in the development of negative charge inside the cell by making the membrane impermeable to positively charged ions.
