Final Exam- Endocrine System

  1. Protein hormones include:





    D) A & B
  2. All protein hormones work through




    C) Second messengers
  3. In general, second messengers work through




    C) Cyclic AMP
  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
    d)G protein becomes activated, amount of cAMP decreases,
    receptor activates D-cAMP, protein hormone binds to the receptor
    • a)Protein hormone binds to the receptor, receptor activates
    • D-cAMP, amount of cAMP decreases, G protein becomes activated

  12. Which hormone is produced by the suprarenal medulla?



    C) all of these
  13. Cyclic-AMP functions as a second messenger to



    C) open ion channels and activate key enzymes in the cytoplasm
  14. ACTH stimulates the release of



    B) steriod hormones by the suprarenal glands
  15. Growth is affected by:




    D) all of these
  16. Effects of thyroid hormones



    C) all of these
  17. Calcitonin _____ the amount of Ca ions in the body, Parathyroid hormone _______ the amount of Ca ions in the body.
