<!-- BG model of cAMP with effects from Gs (B1AR) and Gi (muscarinic), based on saucerman2003
 Assume the cAMP is the same isoform to be affected by either G protein's alpha subunit.
 Assume only one PDE isoform (the one from Saucerman)
 Assume one form of adenylyl cyclase
 Assume one cytosolic compartment
 all other reactions from Saucerman (e.g. FSK, IBMX) are included. -->
