How coffee or caffeine keeps us awake?
We, people, perform our daily activities like thinking, planning, working, watching TV, doing homework, playing, etc. when we perform these activities a by-product adenosine is produced. Adenosine slows down the brain activity and is responsible for our sleepy mood.
In our brain, there are adenosine receptors which are perfectly structured according to the size of adenosine. When adenosines get connected to these receptors, it activates them after which our brain works slowly and we feel sleepy or lack of energy. The more adenosine there is the more tired and sleepy you will feel. While you sleep the concentration of adenosine declines and brings wakefulness.

After consumption of coffee, we don’t feel sleepy because coffee contains caffeine explained above. Caffeine is a drug, after digestion, it reaches to our brain. Caffeine is as similar to adenosine in structure. Being similar, caffeine binds itself to adenosine receptors and blocks the way of adenosine to receptors. Hence, adenosine does not bind to the receptors; after then our receptors work brightly, energized, slow brain activity gets removed and we remain awake and feel fresh.
