What is the difference in impulse transmission between electrical synapses and chemical synapses?

What is the difference in impulse transmission between electrical synapses and chemical synapses?
  1. Impulse transmission across an electrical synapse is always slower than that across a chemical synapse
  2. Impulse transmission across an electrical synapse is always faster than that across a chemical synapse
  3. Impulse transmission across electrical and chemical synapses is the same
  4. There is no difference in impulse transmission between electrical and chemical synapses

Solution

Impulse transmission across an electrical synapse is always faster than that across a chemical synapse because electrical current can flow directly from one neuron into the other. Chemical synapses, on the other hand, rely on the release of neurotransmitters to transmit impulses.
