Question says:
Consider the following: ATP->cyclic AMP

The enzyme that catalyzes this reaction is called adenylyl cyclase. This enzyme is inactive until which hormone binds?
a) Trypsin
b) Glucagon
c) Epinephrine
d) FSH
e) LH

Answer says its epinephrine that activates this enzyme. But when I searched on FSH affects on this pathway I came across this:

And

Both of these seem to suggest that FSH (among others) activates G protein and leads to cAMP. Or maybe it does the opposite? Is there a list of activators and inhibitors?

Sorry I looked for videos but they all say "hormone" binds to Gprotein yada yada yada without telling me which hormones and their affects.

FSH among others can activate it, but epinephrine is the main one you're traditionally taught activates it. You can find evidence of other hormones activating the pathway but it's far less common and not really taught at the level of biology needed for the exam. FSH can technically be correct, but epinephrine is the "best" answer.
