NEET Zoology Synaptic Transmission MCQ Question
Consider a diagram showing a chemical synapse with a synaptic cleft between the pre-synaptic and post-synaptic neurons. Which of the following best describes the role of neurotransmitters in this synaptic transmission process?
They directly carry electrical impulses across the synaptic cleft.
They bind to specific receptors on the post-synaptic membrane to open ion channels.
They cause the immediate fusion of pre-synaptic and post-synaptic membranes.
They close ion channels on the post-synaptic membrane to prevent ion exchange.
Correct Answer
Detailed Explanation
Neurotransmitters released from the pre-synaptic neuron bind to specific receptors on the post-synaptic membrane, opening ion channels and allowing ions to generate a new potential.
