A Cell Has Channels for Na⁺,K⁺,and Cl^- in Its Plasma

Multiple Choice

A cell has channels for Na⁺,K⁺,and Cl^- in its plasma membrane.The resting membrane potential is -60 mV (cell interior negative) .The intracellular and extracellular concentrations for these ions,as well as the calculated Nernst potentials,are listed as follows: A drug is applied to the cell that increases the permeability of the cell by Cl^- (i.e.,it opens Cl^- channels) .What effect will this drug have on the net movement of Cl^- across the plasma membrane?

A) Net Cl^- movement out of the cell will be increased.
B) Net Cl^- movement into the cell will be increased.
C) There will be no change in the net movement of Cl^-.
