Question

During synaptic transmission of nerve impulse, a neurotransmitter (P) is released from synaptic vesicles by the action of ions (Q). Choose the correct P and Q

• A. P - acetylcholine, Q - $C{a}^{2+}$
• B. P - acetylcholine, Q - $N{a}^{+}$
• C. P - GABA, Q - $N{a}^{+}$
• D. P - cholinesterase, Q - $C{a}^{2+}$

Answer 1

The correct option is A P - acetylcholine, Q - $C{a}^{2+}$

$C{a}^{2+}$ is responsible for the release of neurotransmitter acetylcholine from the axon terminal by rupturing the synaptic vesicle.
