2. What will be the outcome if a cell being treated with ouabain ? (A) The cells will be maintained at isotonic condition (B) Due to drug block the voltage-dependent sodium channel, the cells will eventually shrink (C) Ouabain works on potassium leaking channel, cells will swell (D) Due to Na+-K+ pump blockade, high solutes within the cells will drive in water and cells will eventually swell and burst
