This short video uses the example of adenosine and caffeine to introduce two key concepts in pharmacology: the agonist and the antagonist. Both, adenosine, and caffeine molecules bind to adenosine receptors on the neurons. Caffeine, the antagonist, blocks the receptor, while adenosine, the agonist, produces the biological response upon binding.
