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 the ...

increased rate of passive uptake, with the possibility of active uptake depending
on the actual vapor activity encountered in this microclimate. The behavior
