The amount of cAMP generated in the cytoplasm is dependent on the activity of adenylyl cyclase, which catalyzes the conversion of ATP to cAMP, as well as the activity of phosphodiesterase, which breaks down cAMP. Additionally, the length of time the GTP remains bound to the Gα-protein is also a factor in determining the amount of cAMP generated, making it necessary to choose all of the above (D).
