Question

caffeine mimics a chemical in the body called adenosine, which can bind to the adrenal glands and initiate the release of adrenaline (epinephrine). the release of adrenaline may lead to which of the following?
correct answer(s)
release of glucose into the bloodstream a feeling of fear
increased blood flow a feeling of stress
incorrect answer(s)

Explanation:

Adrenaline (epinephrine) triggers physiological responses for energy mobilization and stress adaptation. It stimulates glucose release (for energy), increases blood flow (to muscles/organs), and induces stress-related feelings. Fear is not a direct standard effect of caffeine-adrenaline pathways here.

Answer:

release of glucose into the bloodstream, increased blood flow, a feeling of stress
