NEET Zoology Synaptic Transmission MCQ Question
Which of the following statements about synaptic transmission are correct?
Chemical synapses involve neurotransmitter release and can create excitatory or inhibitory potentials.
Electrical synapses allow direct electrical current flow between neurons through a synaptic cleft.
Neurotransmitters bind to receptors on the pre-synaptic membrane to initiate a new potential in the post-synaptic neuron.
The transmission of an impulse across chemical synapses is always faster than across electrical synapses.
Correct Answer
Detailed Explanation
Statement A is correct because chemical synapses involve neurotransmitter release that can lead to either excitatory or inhibitory responses. Statement B is correct as well, but statement C is incorrect because neurotransmitters bind to receptors on the post-synaptic membrane, not the pre-synaptic membrane. Statement D is incorrect as electrical synapses transmit impulses faster than chemical synapses.
