A chemical called ouabain inhibits the Na/K ATPase (the sodium-potassium pump).  What would happen to glucose concentrations in the extracellular fluid (not the gut lumen) after exposure to ouabain, and why?   Ouabain would cause intracellular sodium levels to rise, which would reduce the active transport of glucose from the gut, thereby decreasing glucose in the extracellular fluid. Ouabain would cause extracellular sodium levels to rise, which would reduce the active transport of glucose from the gut, thereby decreasing glucose in the extracellular fluid. Ouabain would cause intracellular sodium levels to rise, which would reduce the active transport of glucose from the cell to the extracellular fluid.

Ouabain would cause intracellular sodium levels to rise, which would enhance the active transport of glucose from the gut, thereby increasing glucose in the extracellular fluid.
