Question

function of tight Junction​

Answer 1

Their most important functions are to help cells form a barrier that prevents molecules from getting through, and to stop proteins in the cell membrane from moving around. Tight junctions are often found at epithelial cells, which are cells that line the surface of the body and line body cavities. Not only do epithelial cells separate the body from the surrounding environment, they also separate surfaces within the body. Therefore, it is very important that the permeability of molecules through layers of epithelial cells is tightly controlled.

hope it helps you.

Answer 2

Tight junctions help in stoppage of substances from leaking to other cells.
