- The hormone mechanism which results in the release of intracellular Ca++ is the: Question options: PIP 2nd messenger mechanism humoral mechanism 2nd messenger – adenylate cyclase mechanism Steroid hormone mechanismOverexpression 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…The hormone mechanism which results in the release of intracellular Ca++ is the: 2nd messenger – adenylate cyclase mechanism PIP 2nd messenger mechanism O humoral mechanism Steroid hormone mechanism
