Beginning at the synapse of a neuron, place the following events in neuronal signaling in the correct sequence.
1) Ion channels bind the ligand and open.
2) Na⁺ is pumped out of the cell and the membrane potential is restored.
3) Acetylcholinesterase breaks down acetylcholine.
4) Na⁺ enters the postsynaptic cell and the membrane potential changes.
5) Acetylcholine is released into the synapse.
6) Na⁺ ion channels close.
