If caffeine binds to the adenosine receptors in the brain does that mean coffee doesn’t wake you up but keeps you from getting more tired?

Question

Would this be classified as a biology question? XD

Answer 1

Here’s something you might be missing:

Caffeine *also,* in addition to the fact that it blocks adenosine, blocks the transmission of another chemical called GABA, or *γ-aminobutyric acid*, which is responsible for inhibiting neuronal activity — slowing down your brain.

Additionally, in blocking adenosine, caffeine also promotes the release of a couple other neurotransmitters, further adding to caffeine’s stimulant effect.
