The following questions refer to comparative concentrations, permeabilities, and potentials under various circumstances. Indicate the relationship between the two items listed in each situation by following answer code.
-A. amount of Na? transported out of the cell by the Na?-K? pump
B. amount of K? transported into the cell by the Na?-K? pump
A)A is greater than B
B)B is greater than A
C)A and B are equal

Question

Quizplus · Accepted Answer

The Na+-K+ pump moves 3 Na+ ions out of the cell and 2 K+ ions into the cell, thus the amount of Na+ transported out of the cell by the pump (A) is greater than the amount of K+ transported into the cell (B).
