    (this multiple choice question has been scrambled)
  4. Which is in the right order?

    a)Protein hormone binds to the receptor, receptor activates
    D-cAMP, amount of cAMP decreases, G protein becomes activated
    b)Protein hormone binds to the receptor, amount of cAMP
    decreases, receptor activates D-cAMP, G protein becomes activated
    c)G protein becomes activated, receptor activates D-cAMP,
    amount of cAMP decreases, protein hormone binds to the receptor
