Question

Quizplus · Accepted Answer

Caffeine primarily works by blocking the action of a neurotransmitter called adenosine, which promotes sleep and relaxation, rather than causing more neurotransmitters to be released. This blockage leads to an increase in the activity of other neurotransmitters like dopamine and norepinephrine, which enhances alertness and energy, but it's not about causing more neurotransmitters to be released.
