Current Question (ID: 14946)

Question:

Five events in the transmission of nerve impulse across the synapse are given– A. Opening of specific ion channels allows the entry of ions, a new action potential is generated in the post synaptic neuron. B. Neurotransmitter binds to the receptor on post synaptic membrane C. Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter releases into synaptic cleft D. Depolarization of pre-synaptic membrane E. Arrival of action potential at axon terminal. In which sequence do these events occur?

Options:

1. E → D → C → B → A
2. A → B → C → D → E
3. A → B → D → C → E
4. E → D → C → A → B
