Receptor sites are like locked doors that only certain neurotransmitter keys can unlock. At a synapse, the neurotransmitter is released into the synaptic cleft, and it must bind to a specific receptor site on the postsynaptic neuron for the signal to continue. The receptor site is like a lock on a door, and only the correct neurotransmitter can fit into the lock and activate the neuron.
