Differentiate between chemical and electrical synapses and explain the role of neurotransmitters at chemical synapses.

Differentiate between chemical and electrical synapses and explain the role of neurotransmitters at chemical synapses.

• A. Electrical synapses use neurotransmitter release across a synaptic cleft.
• B. Electrical synapses use gap junctions for direct electrical communication; chemical synapses use neurotransmitter release across a synaptic cleft; Neurotransmitters bind postsynaptic receptors to propagate a signal.
• C. Electrical synapses involve chemical signaling across a synaptic cleft.
• D. Chemical synapses transmit signals without receptors.
