  1. The Effect of Caffeineon Test Performance A Physiological Test

  2. Broad Question

  3. Caffeine • Caffeine is a methylxanthine molecule that has physiological effects on the body when ingested. • Caffeine is the world’s most commonly consumed psychoactive substance (Gilbert, 1984).

  4. Caffeine in Coffee • The annual world consumption of coffee exceeds four million tons. • The average consumption in theUnited States is 206 mg per day; 10% of the adult population consumes more than 1000 mg per day. • The average amount of caffeine in a regular 8 oz. coffee ranges from 90-120 mg.

  5. Research that has been done • Topic and conclusion

  6. Purpose –why oh why

  7. Hypotheses

  8. OUR EXPERIMENT

  9. OUR RESULTS

  10. Caffeine inhibits the action of cyclic nucleotide phosphodiesterase and leads to an increase in cAMP Caffeine and Your Body An increase in cAMP could mean the up-regulation of the effects of adrenaline

  11. Caffeine and Your Body Caffeine is an adenosine antagonist that blocks adenosine receptors –By blocking adenosine receptors caffeine decreases the promotion of sleep and increases the activity of neurotransmitters dopamine and glutamate   –Adenosine is a vasodilator and if blocked by caffeine; MAP and consequently heart rate will increase.
