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 cell has channels for Na<sup>+</sup>,K<sup>+</sup>,and Cl<sup>-</sup> 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<sup>-</sup> (i.e.,it opens Cl<sup>-</sup> channels).What effect will this drug have on the net movement of Cl<sup>-</sup> across the plasma membrane? A)Net Cl<sup>-</sup> movement out of the cell will be increased. B)Net Cl<sup>-</sup> movement into the cell will be increased. C)There will be no change in the net movement of Cl<sup>-</sup>.
