Study the diagram of synapse -
I. Which numbered label indicates the location of the receptor molecules
II. Which number points to synaptic vesicles
III. Which number points to neurotransmitter
IV. Which number points to the synaptic cleft
I-C, II-A , III-B ,IV-D

Why (A) is correct:
I. C indicates the receptor molecules on the post-synaptic membrane, which bind to neurotransmitters.
II. A points to the synaptic vesicles, which store and release neurotransmitters.
III. B represents the neurotransmitter molecules being released into the synaptic cleft.
IV. D clearly labels the synaptic cleft, the space between the pre-synaptic and post-synaptic neurons.
Why other options are wrong:
B) Incorrectly identifies B as receptor molecules and C as neurotransmitter.
C) Incorrectly identifies D as neurotransmitter and B as synaptic cleft.
D) Incorrectly identifies D as synaptic vesicles and A as neurotransmitter.
Common Mistake: Students often confuse the neurotransmitter molecules with the receptor molecules or the synaptic vesicles.
NEET Tip / Mnemonic: Remember that vesicles (A) release neurotransmitters (B) into the cleft (D), which then bind to receptors (C) on the next neuron.
Correct Answer: (A)
