NEET Zoology Synaptic Transmission MCQ Question
In synaptic transmission, if the distance across the synaptic cleft is 20 nm, how does the speed of impulse transmission across a chemical synapse compare to an electrical synapse?
Chemical synapse is slower due to synaptic cleft distance.
Chemical synapse is faster than electrical synapse.
Both synapses transmit impulses at the same speed.
Speed is independent of the synaptic cleft distance.
Correct Answer
Detailed Explanation
The NCERT context states that impulse transmission across an electrical synapse is always faster than across a chemical synapse, partly due to the synaptic cleft in chemical synapses.
