A cell is bathed in an isotonic NaCl solution that contains 5 mmol/L of glucose.The intracellular concentration of glucose is 10 mmol/L.What is the most likely mechanism for the transport of glucose across the plasma membrane into this cell? A)Glucose uniporter B)Na⁺-glucose symporter C)Na⁺-glucose antiporter D)Diffusion of glucose through the lipid bilayer of the membrane

Question

Quizplus · Accepted Answer

The Na⁺-glucose symporter is likely used because it can transport glucose into the cell against its concentration gradient by coupling with the inward movement of Na⁺ down its gradient.
