What type of junctional complex will prohibit paracellular transport?
A)tight junctions
B)adherens junctions
C)desmosomes
D)gap junctions

Question

Quizplus · Accepted Answer

Tight junctions create a barrier between cells which prevents the passage of molecules and ions between cells. They are the most effective type of junctional complex in prohibiting paracellular transport. Adherens and desmosomes aid in cell-cell adhesion but do not act as barriers between cells. Gap junctions allow for communication between cells by allowing small molecules and ions to pass through.
