Gap junctions, neurotransmitters, paracrines, and hormones are all mechanisms by which cells do what?Multiple choice question.ReproduceCommunicateProduce energyAttach to other cells

Which of these descriptions about gap junctions are TRUE? Choose all the correct answers.Group of answer choicesThey allow cells to be electrically continuous for rapid communication of electrical impulses e.g. in optical relay neurons.They allow for co-ordinated behaviour of tissue e.g. co-ordination of heart beat.They can be voltage or ligand gated.They actively generate electrical potentials.

The is a gap between two neurons where neurotransmitters are released.
