Select the incorrect statement regarding synapses:
Options
- AElectrical current can flow directly from one neuron into the other across the electrical synapse
- BChemical synapses use neurotransmitters
- CImpulse transmission across a chemical synapse is always faster than that across an electrical synapse
- DThe membranes of presynaptic and postsynaptic neurons are ibn close proximity in an electrical synapse
Correct answer
C. Impulse transmission across a chemical synapse is always faster than that across an electrical synapse
Step-by-step solution
The major difference between a chemical and an electrical synapse is that in a chemical synapse, the nerve impulse is transmitted chemically via neurotransmitters, whereas in an electrical synapse a nerve impulse is transmitted electrically via channel proteins. Chemical synapses use the release of chemical neurotransmitters to propagate signals from one neuron (presynaptic) to another (postsynaptic). The electrical synapses are specialised connections between neurons that facilitate direct ionic and small metaboli
