Signal at receptor males a subunit dissociate form b+y. GTP-GDP.this binds to adenyl cyclase and activates in turning ATP->cyclicAMP. cAMP binds to protein kinase A. R and enzyme separate. enzyme can then phosphorylate aa to create metabolic enzymes.

Guanine nucleotide binding proteins.

Receptor activation of phosphorylase C.
Adrenaline binds. GTP activated, which activated phosphorylase C. ionsitol phospholipid is phosphorylated. binds and opens Ca2+ channel.NT release in brain. activates PKC to phosphorylates proteins.

What are G-protein coupled receptors.
e.g. B-adrenergic. outside loops bind to signals plasma membrane. with a G-protein interaction domain. Then second messengers.
