What strategy/structure prevents Na /Glucose symporters from laterally diffusing from the apical side to the lateral or basal sides of the cell?
a. Tight junctions form a ring of protein around the cell which connects to neighboring cells. This forms a physical barrier restricting lateral diffusion within the membrane.
b. The Na+/Glucose symporters are anchored to the apical side, where they are originally delivered through vesicular trafficking, through protein-protein interactions with the cytoskeleton.
c. Extracellular matrix proteins unique to the intestinal lumen side interact with extracellular side of the Na+/Glucose symporters.
d. None of these
