Question

Quizplus · Accepted Answer

Gap junctions are specialized protein channels that create cytoplasmic bridges between adjacent cells. These channels permit the exchange of small molecules, including glucose and ions, between the two cells. Tight junctions, desmosomes, and zonula occludens are types of cell junctions that do not allow for the passage of molecules between cells.
