Adenosine acts as an autocoid, and virtually every cell contains adenosine receptors within the plasma membrane. Adenosine exerts complex actions. It inhibits the release of neurotransmitters from presynaptic sites but works in concert with norepinephrine or angiotensin to augment their actions. Antagonism of adenosine receptors by caffeine would appear to promote neurotransmitter release."(Coffee House) In other words, the molecular structure of the caffeine molecule is similar to that of adenosine. *
This similarity results in the caffeine molecule binding to the nerve cell membrane. Therefore, the signal to stop producing adenosine that would have been sent by the adenosine becomes blocked, which results in a surplus of adenosine and explains the stimulatory effects of caffeine.
