NEET 2026 (Phase 1) · BiologyPrevious Year Question
The specific receptors for neurotransmitters in a synapse are present on __________.
- A.Schwann cell
- B.Pre-synaptic membrane
- C.Myelin sheath
- D.Post-synaptic membrane✓
Correct Answer
(D) Post-synaptic membrane
Solution & Explanation
Answer: (d) Post-synaptic membrane. Solution: When an impulse reaches the axon terminal, synaptic vesicles fuse with the membrane and release neurotransmitters into the synaptic cleft. These neurotransmitters then bind to their specific receptors present on the post-synaptic membrane, opening ion channels and generating a new potential. Thus the specific neurotransmitter receptors are located on the post-synaptic membrane.
