Question

Quizplus · Accepted Answer

Caffeine is a stimulant that blocks adenosine receptors in the brain, which would normally promote sleepiness and lower arousal levels. As a result, caffeine increases the activity of dopamine and other neurotransmitters in the prefrontal cortex, leading to heightened cognitive functioning and a sense of wakefulness. Melatonin is a hormone that regulates sleep-wake cycles and would be inhibited by caffeine, while serotonin is not directly impacted by caffeine's mechanisms of action.
