What hormone prolongs and intensifies the sympathetic response during stress by increasing heart rate and raising blood glucose?
A
Epinephrine
B
Glucocorticoid
C
T3 and T4
D
ADH
Explanation: 

Detailed explanation-1: -Epinephrine (adrenaline)-Produced by the adrenal medulla. Works with the sympathetic nervous system to help the body respond to a threat. Cortisol-Produced by the adrenal cortex. Signals organs to regulate blood glucose levels so the body can have the energy it needs to stay on high alert.

Detailed explanation-2: -When the body is stressed, the SNS contributes to what is known as the “fight or flight” response. The body shifts its energy resources toward fighting off a life threat, or fleeing from an enemy. The SNS signals the adrenal glands to release hormones called adrenalin (epinephrine) and cortisol.

Detailed explanation-3: -Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies. Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues.

Detailed explanation-4: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-5: -Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream. This gets your body ready for a “fight or flight” response.
