Select the incorrect statement regarding synapses :

1. Impulse transmission across a chemical synapse is always faster than that across an electrical synapse.

2. The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse.

3. Electrical current can flow directly from one neuron into the other across the electrical synapse.

4. Chemical synapses use neurotransmitters

Answer: 1. Impulse transmission across a chemical synapse is always faster than that across an electrical synapse.

Key idea: Electrical synapses are the faster ones.

In an electrical synapse the membranes are very close and current flows directly, so transmission is faster. A chemical synapse needs neurotransmitter release and diffusion across the synaptic cleft, which takes more time. So option 1 is incorrect.
