    All the regulatory subunits now have cAMP bound. This state is ready to dissociate and to release the catalytic subunit.

    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.

    The complex starts to dissociate and release the catalytic subunit C. This has to be fast, as the activation of PKA by cAMP is also fast.
