Which hormone prepares the body for a quick response in an emergency?
Answer and explanation
Correct answer: Adrenaline
The governing concept is the emergency or fight-or-flight response. In sudden danger, adrenaline released by the adrenal glands increases heart rate, breathing readiness, and the supply of glucose and blood to active muscles. Thus, option A is correct. Insulin regulates blood glucose, thyroxine mainly influences metabolism, and auxin is a plant hormone, so they do not provide the characteristic rapid emergency response in humans.
