Answer:

The correct answer would be adrenal gland.

Epinephrine or adrenaline is the enzyme secreted from medulla of the adrenal gland.

Epinephrine enzyme prepares a person for fight and flight situations.

It acts on sympathetic nervous system and increases the cardiac output of a person, blood flow towards the muscles, pupil dilation response, and blood glucose levels.

The sympathetic nervous system reacts to a perceived threat and activates the fight or flight response. This activation releases epinephrine, a hormone secreted by the adrenal glands, especially the adrenal medulla.
