Summary Introduction
Introduction: Epinephrine is a hormone produced by adrenal gland and some specific neurons. It is also known as adrenaline and it is a major hormone produced during stress condition. It is also commonly known as “Flight, Fright and Fight hormone” as its amount increases during emergency conditions. It is also used as a drug due to its various important functions.

Why does epinephrine bind its receptor in a different location than cortisol binds its receptor?
A.
The receptor binding site of epinephrine must be extracellular because the cell’s membrane is a barrier that prevents epinephrine from reaching any intracellular binding sites.
B.
The membrane blocks cortisol from entering the cell, therefore cortisol must bind the receptor on the cell’s extracellular surface.
C.
Cortisol easily passes through the cell’s plasma membrane. Therefore, the cortisol receptor is found intracellularly.
D.
Epinephrine can dissolve across the plasma membrane and bind its intracellular receptor.
E.
Both A&C
F.
Both B&D
Hormone X appears to regulate the blood concentration of chemical Y via a negative feedback loop. a. Predict what happens to the secretion of hormone X when the blood concentration of chemical Y decreases. b. What effect will this likely have on the blood concentration of chemical Y?c. Predict what happens to the secretion of hormone X when the blood concentration of chemical Y increases.
What is the main difference between organizing effects and activating effects of hormones?A. Organizing effects are long-lasting, whereas activating effects are temporary.B. Organizing effects alter brain activity, whereas activating effects alter other parts of the body.C. Organizing effects are excitatory, whereas activating effects are inhibitory.D. Organizing effects depend on estrogens, whereas activating effects depend on androgens.

- Which statements describe how systems interact to produce the fight-or-flight response?Select the two correct answers.
