Cyclic $AMP$

Vedclass · Answer

(B) Peptide hormones are water-soluble and cannot cross the plasma membrane of the target cell.They bind to specific receptors present on the surface of the plasma membrane.This binding triggers the generation of second messengers,such as cyclic $AMP$ $(cAMP)$,$IP_3$,or $Ca^{2+}$,inside the cell.These second messengers then regulate cellular metabolism and physiological responses.Therefore,the action of peptide hormones is mediated by cyclic $AMP$.
