Identify the correct statements regarding the sequence of events taking place during transmission of impulse across a chemical synapse as shown in the given figure:
1. Only I, II and III
2. Only I, III and IV
3. Only II, III and IV
4. I, II, III and IV
| I: | The action potential, generated due to the depolarization of the axonal membrane, arrives at the axon terminal. |
| II: | Potassium ions enter the synaptic knob. |
| III: | Synaptic vesicles are activated and release neurotransmitter in the synaptic cleft. |
| IV: | Neurotransmitter binds to the receptor on the post-synaptic membrane. |
1. Only I, II and III
2. Only I, III and IV
3. Only II, III and IV

Hints
What would be true regarding the structure shown in the given figure?
| 1. | It is a chemical synapse and there is unidirectional transmission of impulse across it. |
| 2. | It is a chemical synapse and a chemical neurotransmitter is involved in the transmission of impulse across it. |
| 3. | It is an electrical synapse and it is relatively slower than the chemical synapse. |
| 4. | It is an electrical synapse, and although faster than the chemical synapse, is rare in human body. |
