Epinephrine initiates a signal transduction pathways that produces cyclic AMP (cAMP) and leads to the breakdown of glycogen to glucose, a major source of energy for cells. Glycogen breakdown is only part of the flight-or-fight response that epinephrine brings about because the overall effect on the body includes an increase in heart rate and alertness, as well as a burst of energy. Given that caffeine blocks the activity of cAMP phosphodiesterase, this suggests that caffeine blocks the epinephrine pathway that was just described.
Propose a mechanism by which caffeine ingestion leads to heightened alertness and sleeplessness.
