빈칸 문제 투척 (듄 아님)

Suprisingly, caffeine is not a typical stimulant; it does not push brain cells to become alert, and perform better Caffeine, rather,
 ------------------------------.Instead of triggering the release of "up" chemicals, it blocks the action of the neurotransmitter,
adenosine,that ordinarily tells the brain to quiet down and go to sleep. Since the caffeine molecule chemically resembles adnosine,
it can occupy brain cell receptor sites, displacing adenosine. This prevents adenosine from suppressing the alertness caused by
"upper" neurotransmitters, such as dopamine. Thus, caffeine, by disguising itself as adenoise, fools brain cells into remaining in
a persistent state of excitability. A little caffeine goes a long way. Experts say that the caffeine in a couple of cups of coffee can knock out
half the brain's adenoise receptors for a couple of hours, keeping your brain on high alert.

1. works in a roundabout way
2. performs with other stimulants
3. takes part in many brain function
4. function differently according to its type
5. fosters various effects of chemicals
