I understand that it doesn’t allow adenosine to connect to the receptors, but if the receptor doesn’t know which molecule connected, it should unleash the same reaction, right?
In: Chemistry
Thats because your idea is wrong, not every molecule causes a reaction when connected its only agonists that cause the receptor to change what its doing. Caffeine probably is an antagonist which stops the action of that receptor but I didnt look into what adenosine or caffeine does exactly.
In the simplest terms, Adenosine has a reaction with the receptor, caffeine does not have a reaction. Thus, it blocks adenosine from being effective.
It’s not that caffeine does the opposite, it just ‘plugs’ the hole and keeps adenosine from doing its job.
