The function of the gap junction is to
| 1. | performing cementing to keep neighbouring cells together. |
| 2. | faciliate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules. |
| 3. | seperate two cells from each other. |
| 4. | stop substance from leaking across a tissue. |
