Caffeine

The Things that contain Caffeine i.e. some soft drinks activates the Brain functioning, the molecular detail of this activation is given below
Caffeine clearly produces a state of arousal in the central nervous system. High levels appear to block the binding of an inhibitory neurotransmitter, adenosine, to the A2A adenosine receptor. In the absence of caffeine, adenosine levels rise during the day, which promotes interaction with its receptor, leading to increasing sleepiness and lack of concentration. When adenosine binds normally to its receptors, it activates the adenylate cyclase cascade, which activates PKA, leading to changes in phosphorylation state of many proteins inside the cell, including protein phosphatase (2A). These changes inhibit neural firing. Caffeine blocks these changes.
it is a seprate discussion that what level of caffeine should be taken and also whether it has some side effects on the body or not.
