What is the correct order for the events of neurotransmitter release from the synaptic terminal?

The correct order for the events of neurotransmitter release from the synaptic terminal is given below ...

Explanation:

1: Depolarization of the terminal membrane,

2: Voltage-gated Ca2+ + channels activated

3: Extracellular Ca2 + enters terminal and binds to sensor protein

4: Change in the conformation of docking proteins

5: Fusion of the vesicle to the plasma membrane, with subsequent release of neurotransmitter into the synaptic cleft.
