Gs | | 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. |

Pathway No. : 196 | 0.25 | 1000 | No | | About 25% of PKA C subunit is dissociated in resting cells without having any noticable activity. Doskeland SO and Ogreid D (1981) Int J Biochem 13(1):1-19 suggest that this is because there is a corresponding amount of inhibitor protein. |

| Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated.
Kd for higher order reaction are not consider. |
