Homework Help: Cell biology, please help today

I'm not sure what order these are when it comes to g-protein activation:

-conformational change in receptor
-hormone binds receptor
-Gs protein has GTP bound
-Alpha and gamma/beta subunits dissociate
-GTP is hydrolyzed to GDP on alpha sububit
-alpha and beta/gamma subunits reassociate
-adenylyl cyclase is activated

I believe the order is:

hormone binds receptor
conformational change in receptor
Alpha and gamma/beta dissociate
G protein bound to GTP
Adenylate cyclase is activated
GTP hyrdrolyzed
alpha and bet/gamma reassociate

im trying to do my project on biology in cells but i cant find it
