Presume that the binding of one molecule of epinephrine to a seven-transmembrane helix (7TM) receptor (as well called the G protein-coupled receptor, or GPCR) results in the activation of 440 G? subunits. In addition, presume that each activated adenylyl cyclase catalyzes the conversion of 20 ATP molecules to cAMP per second. Presume that each G protein activates a single unique adenylyl cyclase. Compute the number of moles of cAMP that are produced per second.
