Which of the following functions is NOT typically associated with cell–cell junctions in epithelial tissue?
Show answer and explanation
Correct answer: Allowing free diffusion of large proteins between adjacent cell cytoplasms
Cell–cell junctions like tight junctions and gap junctions regulate permeability and selective communication; they generally do not allow free diffusion of large proteins between adjacent cell cytoplasms — only small molecules/ions can pass via gap junctions.
