Video: Caffeine and Adenosine

09/02 

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