Question

During synaptic transmission of nerve impulse, neurotransmitter P is released from synaptic vesicles by 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$a^{2+}$

$Ca^{++}$ is responsible for release of neurotransmitters acetylcholine from axon terminal by rupturing synaptic vesicle

So, the correct answer is (A)
