The chemical structure of caffeine is very similar to that of adenine (a component of ATP, DNA, and cyclic AMP). Only the substituents are different. This helps explain caffeine's stimulating effects. It is really close to being an energy metabolite in and of itself! Because of the structural similarities, caffeine can slip right into adenosine receptors, keeping cyclic AMP active rather than it being broken down. When cyclic AMP breaks down, the body's energy supply decreases. Because caffeine fools the body into using enzymes to break it down instead, the cyclic AMP supply remains higher for longer.
