Which hormone prepares the body during fear or danger?
Answer and explanation
Correct answer: Adrenaline
The governing concept is the emergency or fight-or-flight response. During fear or danger, the adrenal glands release adrenaline into the blood. It increases heart rate and breathing rate, directs more blood toward skeletal muscles, and makes stored energy rapidly available. Thus option A is correct. Insulin mainly regulates blood glucose, thyroxine influences metabolism and development, and estrogen is chiefly involved in female reproductive development and functions.
