How does a gap junction facilitate intercellular communication ?

Explanation

Celestial connection facilitates small molecules to pass through from one cell to second cell through intercellular integration. They are hydrophillic pathways between two animal cells which is made up of two cylinder of protein. They are called Connexus. Each Connexus possesses six subunits of protein which surrounds hydrophillic pathway. pH and concentration of `Ca^(+2)` regulate the opening and closing of pathway.
