Question 3

Correct Answer:

Verified

Epithelial cells are able to control and even mediate the transport of substances between the apical and basal areas via occluding junctions between epithelial cells. Substances must pass through the cell to cross the epithelia, and this transcellular path can be highly controlled. Only very small molecules may be able to pass through the occluding junctions and thus take the paracellular path.
