- The anterior pituitary lobe makes how many tropic hormones? What are trophic hormones?
- a if the action of 1 hormone inhibits effect of another
- b thyroid gland
- c if 2 hormones work together to produce a greater effect.
- d secreted by parathyroid gland; increases blood calcium concentration; also causes production of enzymes that activate a prehormone that ultimately becomes vitamin D
- e 6; hormones that cause target tissues to enlarge and they maintain the size of those tissues.
5 Multiple Choice Questions
- thyroid hormones; ATP is the primary byproduct of thyroid hormones that increasing oxygen consumption in cells (which act as last electron acceptors).
- calcium inside the cell; high levels of calcium inside the cell can activate many different pathways causing "chaos"
- before gene transcription (making of mRNA) can occur, two different steroid hormones have to bind to the two half-sites on the hormone response element (one hormone each)

5 True/False Questions
Melatonin → an amine hormone excreted from brain into blood & effects daily rhythms
Desensitization (down regulation) → causing receptors to be pulled into cell no longer able to receive hormone; there will more more hormone available, but not much of an effect; occurs following long exposure/high levels
When looking at chemical classification, what are the 4 possible categories of hormones? → steroids, amines, polypeptides and glycoproteins
Starting in the blood stream, give the mechanism of steroid hormones being used, ending in the steroid hormone response (6). → 1) Steroid hormones travel in the blood stream attached to carrier proteins. 2) Once they pass through the membrane of a cell on their own, 3) the steroid attaches to a nuclear receptor protein that translocates it to the nucleus 4) causing the production of mRNA through transcription and then 5) the production of protein synthesis through translation. 6) This protein synthesis is what causes the steroid hormone response
Although some endocrine hormones and tissues are not related to one another, what do they have in common? → Come from hypothalamus; they tell anterior pituitary to release one of its 6 trophic hormones into the blood
