Which of the following statements regarding transcellular transport is NOT true? The movement of glucose into the blood is mediated by GLUT2 transporters. Tight junctions are specialized regions of the plasma membrane that mediate separation of the apical and basolateral membranes. Transcellular transport moves glucose across epithelia asymmetrically. The Na+ concentration gradient across the membrane is the only gradient required to drive uptake of glucose from the intestine.

Tight junctions are specialized regions of the plasma membrane that mediate separation of the apical and basolateral membranes.

Explanation:

Transcellular Transport is the pathway in intestinal epithelial cells where particles move from one cell to another depending on the physicochemical properties of the particles passing both the the apical membrane and basolateral membrane. Tight junctions create a paracellular barrier in epithelial and endothelial cells protecting them from the external environment
