Give the steps to chemical synapse:

Answer variants:
On the postsynaptic membrane, transmitters bind to receptors. Then, ion channels are opened.
Calcium-mediated exocytosis releases neurotransmitters.
Opening voltage-gated calcium ion channels, then they are entering into the presynaptic terminal
Ion transport across the postsynaptic membrane. Due to this, membrane potential shifts in the postsynaptic membrane. Results in the formation of synaptic potential generation.
At the presynaptic nerve terminal, the action potential arrives.
