Which type of junction contributes the most to the polarization of epithelial cells?

Question

Quizplus · Accepted Answer

Tight junctions form a seal between epithelial cells, preventing the movement of molecules between them. This creates an asymmetry in membrane composition and function, which contributes the most to the polarization of epithelial cells. Adherens junctions and desmosomes provide mechanical strength and allow for cell-cell adhesion. Gap junctions allow for communication and ion transfer between cells. While each of these junctions plays an important role in epithelial tissue function, tight junctions are most essential for creating and maintaining cell polarity.
