Question
Select the incorrect statement regarding synapses:
Impulse Transmission across a chemical synapse is always faster than that across an electrical synapse.
The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse.
Electrical current can flow directly from one neuron into the other across the electrical synapse.
Chemical synapses use neurotransmitters.
According to the text, impulse transmission across an electrical synapse is always faster than that across a chemical synapse . Therefore, the statement claiming chemical transmission is faster is incorrect. The text confirms the other statements: in electrical synapses, membranes are in very close proximity and current flows directly , while chemical synapses involve neurotransmitters .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Neural Control and Coordination. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
