This model consists of receptor-ligand interaction, G-protein activation, Adenylyl cyclase mediated formation of cAMP and activation of PKA in the neuron. Demonstration programs using this model described in Bhalla US. (2004) Biophys J. 87(2):733-44 to generate a dose-response curve using stochastic calculations are available here.

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.
