Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).
Answer: wherever the wind blows :)
Explantation: the waves go 90 degrees to the left (southern hemisphere) or the right (northern hemisphere)
