How do agonists, antagonists, and reuptake inhibitors all differ
from one another?

A common mechanism for agonists is reuptake inhibition, where the agonist blocks neurotransmitters from reentering the pre-synaptic axon terminal. ... Conversely, antagonists often bind directly to receptors in the synaptic cleft, effectively blocking neurotransmitters from binding.
