Question

The correct sequence of sigl transmission at a chemical sypse:
A. Nerve impulse at syptic end bulb
B. Neurotransmitter molecules released
C. Binding of neurotransmitter molecules to their receptor
D. Postsyptic potential
E. Opens voltage gated Ca$^{2+}$ channels

• A. D, A, B, C, E
• B. D, E, A, B, C
• C. A, B, C, E, D
• D. A, E, B, C, D

Hint:

Syptic Transmission Sequence:
Action Potential (A) $\to \text{Ca}^{2+}$ channels open (E) $\to$ Exocytosis of Neurotransmitter (B) $\to$ Receptor binding (C) $\to$ Postsyptic potential (D).

Answer 1

The Correct Option is D
