What is an agonist?

Agonist from Wikipedia
"An agonist is a chemical that binds to a receptor of a cell and triggers a response by that cell. Agonists often mimic the action of a naturally occurring substance. Whereas an agonist causes an action, an antagonist blocks the action of the agonist and aninverse agonist causes an action opposite to that of the agonist."
