If the extracellular concentration of sodium is always in excess to that of glucose, which of these manipulations would MOST increase the rate of glucose transport into a cell? A. increase in the extracellular concentration of sodium B. increase in the intracellular concentration of sodium C. increase in the extracellular concentration of glucose D. increase in the intracellular concentration of glucosearrow_forwardGlucose can be transported into cells with a glucose/sodium symporter. If the extracellular concentration of sodium is always in excess to that of glucose, which of these manipulations would MOST increase the rate of glucose transport into a cell? A. increase in the extracellular concentration of sodium B. increase in the intracellular concentration of sodium C. increase in the extracellular concentration of glucose D. increase in the intracellular concentration of glucose I believe the correct answer is A because once the extracellular concentration of Na is increase, this will drive the Na-glucose symporter to pump Na down its gradient, which will "pull" the glucose into the cell against its gradient. However, the previous Bartleby answer was B. Please explain why A is not right. Thanks!arrow_forward
