Agonist
Receptors that respond to chemical messengers, e.g. neurotransmitters, may be:
An agonist that binds to the receptor and produces an effect within the cell.
An antagonist that may bind to the same receptor, but does not produce a response, but blocks that receptor to a natural agonist.
For example, Cortisone, C21H28O5, is a corticosteroid hormone receptor agonist.
