Transepithelial transport requires a _____ cell layer.

Question

Quizplus · Accepted Answer

Transepithelial transport requires a cell layer that is both polarized and sealed, meaning that the cells have distinct apical and basolateral membranes and there are tight junctions between the cells to prevent leakage between them. This allows for selective transport of molecules across the epithelial layer. A permeable cell layer would allow molecules to freely move through the cells and not allow for selective transport.
