3.2.2.2 Cyclic AMP dependent phosphodiesterase The level of cAMP in cells is
determined by the activity of adenylate cyclase in synthesizing CAMP from ATP
and cyclic nucleotide phosphodiesterases ( PDE ) in hydrolyzing CAMP to
inactive ...

The critical equilibrium activity ( CEA ; activity = relative humidity / 100 ) is the
activity at which water uptake from the environment equals loss from the body .
For this value to be lower than about 0.99 ( hemolymph activity ) the tick must
have ...

on the actual vapor activity encountered in this microclimate . The behavior ...
