When adrenaline (epinephrine) binds to its integral membrane receptor, this initiates an intracellular signalling cascade, which includes each of the following events (but not necessarily in this order):

GTP binds to the Gα subunit

cAMP is hydrolysed to give AMP

The adrenergic receptor undergoes a conformational change

ATP is converted to cAMP and pyrophosphate

GDP dissociates from the Gα subunit

The Gα subunit binds to adenylyl cyclase

What is the correct order of these events?
