Question

Quizplus · Accepted Answer

Gap junctions are channels made up of protein subunits called connexins that allow for the movement of ions and other small molecules between adjacent cells. This permits communication and coordination between cells, which is important for a variety of physiological processes. Gap junctions do not prevent fluid leakage, stimulate cellular reproduction, or occur only in muscle tissue.
