Detailed explanation-1: -(A) cAMP is the archetypical second messenger. Its levels increase rapidly following receptor-mediated activation of adenylyl cyclase (AC), which catalyzes the conversion of adenosine monophosphate (AMP) to cAMP.
Detailed explanation-2: -So, the correct answer is ‘cAMP’
Detailed explanation-3: -Examples of hormones that use cAMP as a second messenger include calcitonin, which is important for bone construction and regulating blood calcium levels; glucagon, which plays a role in blood glucose levels; and thyroid-stimulating hormone, which causes the release of T3 and T4 from the thyroid gland.
Detailed explanation-4: -cAMP is considered a second messenger because cAMP is used as a common amplifier for signal effects. When a given signal is recognized on the exterior of a cell, it usually activates some surface protein to activate other proteins that can create such second messengers.
