- A __________ is synthesized from amino acids and cannot diffuse across the plasma membrane. a, steroid hormone b. protein hormone c. peptide hormone d. both b and cHormone receptor molecules are the key to understanding specific-ity of hormone action on target cells. Describe and distinguish be-tween receptors located on the cell surface and those located in the nucleus of target cells. Name two hormones whose action is medi-ated through each type of receptor.Give 3 examples of probable endocrine disruptors. Why are endocrine disruptors ofconcern even at very low concentrations?Briefly describe:a) the endocrine system (what biological systems are involved), andb) 3 ways endocrine disruptors (EDs) affect the endocrine system
- All of the following statements relating to endocrine signaling are correct EXCEPT:The primary reason for downregulation/desentization of hormone receptors is: O metabolic clearance prolonged exposure abnormally high hormone levels normal physiological levelsUnder in vivo conditions, chronic treatment with a noncompetitive antagonist may lead to the up-regulation of the targeted receptor over time. True False Cytokines are peptides that are generally made in advance by specific types of cells, stored in vesicles, and act as autocrine or paracrine factors. True False Thyroid hormone is stored in an extracellular compartment. True False
- Discuss why the target-cell concept is essential forunderstanding hormone functionPropose an explanation for why defects in a particular hormone cascade pathway observed in patients typically affect the final gland in the pathway rather than the hypothalamus or pituitary.mo Fill in this table for cortisol, aldosterone, testosterone, estradiol, parathyroid gland hormone, calcitonin, calcitriol, thyroxine.

- 1) Hormone pathologies often manifest with elevated or lower hormones. The underlying cause may differ. What symptoms would be associated with hyperthyroidism? 2) Autoimmune disease in which auto-antibodies stimulate the TSH receptor (TSHR) on the thyroid gland. How would this affect levels of TRH, TSH, and TH? Draw out the H-P-T axis to illustrate changes in each hormone. 3) What symptoms would be associated with hypothyroidism? 4) How could this disease be treated? When the thyroid cells are destroyed, they cannot make hormones anymore and TH replacement needs to be given.mo Fill in this table for cortisol, aldosterone, testosterone, estradiol, parathyroid gland hormone, calcitonin, calcitriol, thyroxine.
