Quizplus · Accepted Answer

Catecholamines, such as adrenaline and noradrenaline, are released during stressful situations and activate the sympathetic nervous system. This leads to the fight or flight response, causing the heart to beat faster, increasing blood pressure, and preparing the body to respond to a potential threat. Cortisol, on the other hand, is a stress hormone that can increase blood sugar levels, but it does not activate the pituitary gland or induce the release of ACTH from the pineal gland. Therefore, choice D is the best answer.
