If they are antagonistic, explain the specific opposing functions. A) Calcitonin and Parathyroid hormone B) Oxytocin and Prolactin C) Thyroid Stimulating Hormone (TSH) and Thyroxine (T4)
- Androsterone is a male hormone. Based on its name and suffix, which functional group is present?1) Gross Anatomy and Basic Function of the Endocrine Glands a)Both the endocrine and nervous systems are major regulating systems of the body; however, the nervous system has been compared to a text message, and the endocrine system to mailing a letter. Briefly explain this comparison. b) Chemically, hormones belong chiefly to two molecular groups, the___ and the___ c) If hormones travel in the bloodstream, why don't all tissues respond to all hormones?In the 1950s, Earl W. Sutherland, Jr., and his colleagues carried out pioneering experiments to elucidate the mechanism of action ofepinephrine and glucagon. Given what you have learned in this chapter about hormone action, interpret each of the experiments described below. Identify substance X and indicate the significance of the results.(a) Addition of epinephrine to a homogenate of normal liver resulted in an increase in the activity of glycogen phosphorylase. However, when the homogenate was first centrifuged at a high speed and epinephrine or glucagon was added to the clear supernatant fraction that contains phosphorylase, no increase in the phosphorylase activity occurred.(b) When the particulate fraction from the centrifugation in (a) was treated with epinephrine, substance X was produced. The substance was isolated and purified. Unlike epinephrine, substance X activated glycogen phosphorylase when added to the clear supernatant fraction of the centrifuged homogenate.(c)…
