Question

What type of membrane junction allows ions to pass directly from the cytoplasm of one cell to the cytoplasm of the adjacent cell?

Answer 1

Answer:

Gap junctions allow the passage of ions to pass directly from the cytoplasm of one cell to the cytoplasm of the adjacent cell.

Explanation:

Gap junction helps to maintain the connection between the cytoplasm of two adjacent cell and helps in the passage of solute molecules,electric potential between cells connected by Gap junction.

           Gap junction is a gated channel containing 2 proteins A Connexon  and B Connexin .

            Connexon channel protein helps in the propagation of electric potential between adjacent cells.This protein also allow the movement of second messenger for example ca2+ ion.
