How many cAMP molecules are required to free PKA from its regulatory subunit complex?
Cyclic AMP can be deactivated through cleavage carried out by which enzyme that is inhibited by caffeine?
Myristoylphorbol acetate is a tumor promotor because it enhances cell growth and proliferation through activation of which compound?
Which type of receptor would cause bronchial dilation after binding its ligand?
Membrane-bound guanylyl cyclase is activated by either guanylin or this compound.
In the RTK-Ras pathway, what protein acts as a GEF?
Atrial Natriuretic Factor (ANF) binds to and activates this receptor.
Vasoconstriction is accomplished through activation of _____ adrenergic receptors
GEF (guanine exchange factor) proteins enhance the dissociation of what molecule from Ras?
Where in the body can alpha adrenergic receptors be found?
Which type of receptor would cause heart rate to increase?
True or False: PLC an PI-3K can be regulated by both GPCR's and RTK's.
What molecule closely associates with cytosolic guanylyl cyclase?
Alpha 2 adrenergic receptors use which G-protein?
In a patient with Cholera toxin, what compound is being constitutively produced?
