Identify the following as properties of electrical synapses (ES), chemical synapses (CS), or both (B). a. _____ The plasma membranes of presynaptic and postsynaptic neurons are joined by gap junctions. b. _____ Transmission is unidirectional and delayed. c. _____ A presynaptic neuron and a postsynaptic neuron are involved. d. _____ The use of neurotransmitters packaged into synaptic vesicles is required. e. _____ Transmission is nearly instantaneous and bidirectional.

Step 1
The plasma membranes of presynaptic and postsynaptic neurons are joined by gap junctions. This is a property of electrical synapses, so the answer is ES. b. Transmission is unidirectional and delayed. This is a property of chemical synapses, so the answer is Show more…

Which of the following are characteristics of a chemical synapse? Choose all that apply. (2 points) A. Release of neurotransmitter by exocytosis from the presynaptic neuron B. Receptors for the neurotransmitter are present on the postsynaptic neuron C. The presynaptic neuron and the postsynaptic neuron are physically connected together D. The synaptic cleft is a space separating the presynaptic and postsynaptic neurons

Neurotransmitters _______ A. are electrical charges that move down myelinated axons; B. are released across the nodes of Ranvier to hasten nerve impulse transmission; $\mathrm{C}$. are released when an electrical impulse arrives at the terminal bouton of the postsynaptic neuron; D. diffuse across a synapse and bind to receptors on the cell membrane of the postsynaptic neuron.
Which of the following is a true difference between electrical and chemical synapses? A. electrical synapses are more complex, allowing for more subtle, graded responses in the post-synaptic neuron B. chemical synapses do not rely on or involve the movement of ions across the cell membrane C. chemical synapses are slower than electrical synapses due to the time necessary for diffusion across the synaptic cleft D. electrical synapses but not chemical synapes rely on neurotransmitter GPCRs E. chemical synapses involve the passage of neurotransmitter from the cytoplasm of the pre-synaptic neuron directly into the cytoplasm of the post-synaptic neuron
