Answer:
Na+/glucose symporters.
Explanation:
Na+/glucose symporters helps in transporting the glucose across the membrane. It is a transmembrane protein and glucose transport is an example of secondary active transport Na ions is required to drive the transport of glucose.
As it is a symporter so this protein transport sodium and glucose in the same direction. ATP energy is used to transport the glucose against the concentration gradient. Na+/glucose symporters are present on epithelial cell with binds to both Na and glucose and transport them simultaneously in the epithelial cell. So the right answer is Na+/glucose symporters.
