John has just finished a brutal tour of combat in afghanistan. several of his friends were killed, but he was able to cope and fight on despite the death around him. the two stress hormones at play in john's experience are epinephrine and:

Nor-epinephrine

Explanation:

Nor-epinephrine is a hormone that is also called nor-adrenaline. It is released from the nerve endings of the sympathetic nervous system. These hormones play a role in the sympathetic system. The hormone nor-adrenaline is responsible for the fight and flight situation. In this situation, a person's heart rate increased. In this hormone, a person reacts to a stressful situation. This hormone is made up of cate-cholamine in which it contains catechol and that bound with the amino acid. It works as a neurotransmitter with the hormones in the body.
