Concept explainers
Interpretation:
The role does the second messenger play in a cell stimulated by epinephrine should be determined.
Concept introduction:
Epinephrine (or adrenaline) is a hormone secreted by the medulla of the adrenal glands. It is produced in times of stress such as excitement, danger, noise …
Secondary messengers are short lived intracellular signaling molecules. Elevated concentration of these types of messengers leads to rapid alteration in the activity of one or more cellular enzymes.
cAMP is a cyclic
Enzymes are proteins that increase the
Phosphodiesterase is an enzyme that breaks a phosphodiester bond. This enzyme plays a key role in regulating intracellular levels of the second messenger cAMP and hence cell function.

- why is a cell unable to respond to epinephrine signalingarrow_forwardOverexpression of this receptor in the cells of the adrenal gland causes Cushing's syndrome, a disease caused by the overproduction of cortisol. One strategy that scientists have employed to treat this disease is the use of small molecules that bind to, but do not activate, MC2R. This type of molecule is generically referred to as an antagonist. How can an antagonist bind to the same receptor as ACTH but not activate it? O a. The antagonist can bind covalently while ACTH binds non-covalently O b. The antagonist is only partially complimentary to the binding pocket of MC2R O The antagonist binds to ACTH and blocks it from binding to the receptor properly O d. The antagonist is the exact same structure as ACTH but since it is synthetic it doesn't work One cause of Cushing's syndrome is the inappropriate production of GPCRS in the adrenal gland that are not normally present in those cells. When these receptors are activated they result in the production of cortisol. Which statement about…arrow_forwardWhat is the difference between a G protein and a receptor tyrosine kinase?
