1. They allow cells to be electrically continuous for rapid communication of electrical impulses e.g. in optical relay neurons: TRUE. Gap junctions allow ions and small molecules to pass directly from one cell to another, enabling rapid communication.

2. They allow for co-ordinated behaviour of tissue e.g. co-ordination of heart beat: TRUE. Gap junctions are crucial for many types of cell-to-cell communication, including the coordination of heart muscle contractions.

3. They can be voltage or ligand gated: FALSE. Gap junctions are not gated. They are always open, allowing for continuous communication between cells.

4. They actively generate electrical potentials: FALSE. Gap junctions do not generate electrical potentials. They allow the passive flow of ions and small molecules between cells, which can result in changes in electrical potential, but they do not actively generate these potentials.
