This is a model of the canonical cAMP signaling pathway:
Ligand->Receptor->G-protein->Cyclase->cAMP->PKA.
It also includes phosphodiesterases to balance out cAMP formation.Bhalla US Methods Enzymol. 2002;345:3-23

ATP is present in all cells between 2 and 10 mM. See Lehninger. It is assumed buffered since the metabolic activity will take care of its levels.
