Construct a table to compare the hormones involved in water and
salt balance. Include the site of secretion and molecular structure
of each hormone, the principal stimuli that cause its secretion,
its effect on target cells, and other information you consider
important.
Step by step
Solved in 2 steps
- Give 3 examples of a hormone and provide the following information of each hormone: a. where is the hormone produced? b. target organ of the hormone c. function of hormoneWhich statement correctly identifies how a lipid-soluble hormone that diffuses from the blood and through the interstitial fluid identifies which cells in the tissue to act upon? O The cell closest to the diffusion site. O The presence of a receptor located in the cytoplasm or nucleus specific to the hormone in cells. O The presence of a receptor embedded in the plasma membrane of target cells. O The presence of a channel protein embedded in the plasma membrane for the lipid-soluble hormone to diffuse through. Save for Later 80 F3 F4 F5 F6 8 F7 Attempts: 0 of 3 used F8 F9 Submit Answer F10Hormones are often synthesized and stored in an inactiveform within secretory vesicles. Secretion usually occurs onlywhen the hormone-producing cell is stimulated. Explain theadvantages that this process has over making the hormonemolecules as they are needed.
- Describe the mechanism of hormone response resulting from the binding of a hormone with an intracellular receptor.The kidneys are important regulators of blood volume (and thus MAP) and the ionic composition and pH of plasma . The amount of water reabsorbed or lost is hormonally regulated. Both the amount of blood that is filtered (glomerular filtration rate) and the amount of water that is reabsorbed is determined by hormones binding with receptors. In order to understand why the level of any given hormone is elevated or low in the blood, it is necessary to think in terms of homeostasis loops for each hormone, and what the initial disturbance to homeostasis was. In other words “who started it”! What NON STEROID hormone is produced at the end (but as part of) of the RAS pathway?The kidneys are important regulators of blood volume (and thus MAP) and the ionic composition and pH of plasma. The amount of water reabsorbed or lost is hormonally regulated. Both the amount of blood that is filtered (glomerular filtration rate) and the amount of water that is reabsorbed is determined by hormones binding with receptors. In order to understand why the level of any given hormone is elevated or low in the blood, it is necessary to think in terms of homeostasis loops for each hormone, and what the initial disturbance to homeostasis was. In other words "who started it"! What STEROID hormone is elevated by increased activation of the RAS pathway?
- Suppose that the circulating concentration of hor-mone is 10–10 M and the Kd for binding to its receptor is 10–8M. What fraction of the receptors will have hormone bound?If a meaningful physiological response occurs when 50% ofthe receptors have bound a hormone molecule, how muchwill the concentration of hormone have to rise to elicit aresponse? The fraction of receptors (R) bound to hormone(H) to form a receptor–hormone complex (R–H) is [R–H]/([R] + [R–H]) = [R–H]/[R]TOT = [H]/([H] + Kd).Vasopressin or antidiuretic hormone (ADH) is a peptide hormone synthesized in the a) hypothalamus. This hormone, when present, induces expression of water transport proteins (aquaporins) in the late distal tubule and collecting duct of the kidney to increase water reabsorption. Binding to the receptor triggers an intracellular cyclic adenosine monophosphate (CAMP) pathway. Arrange the following steps of hormone signalling in the proper order by putting 1, 2, 3, etc in the space provided, CAMP activates CAMP-dependent protein kinase (PKA). Recruitment of inactive G-protein made of heterotrimeric subunits which has GDP bound to a-subunit. Conformation change in GPCR. Adenylyl cyclase converts ATP into CAMP. PKA phosphorylates proteins in the cell. A cellular response is seen in the cell. a-subunit with GTP bound activates adenylyl cyclase. Activation of G-protein, thus GDP released an GTP binds to a-subunit. a-subunit of G-protein dissociates from By-dimer. Hormone binding to its…Name the types of chemical makeup possible for hormones and the types of hormone receptos.
- List the major categories of hormones on the basis of their chemical structure. Describe how hormones interact with tissues to produce a response. Describe three methods of regulating the release of hormones.determine the principle involved or color reaction mechanism of each steroid. progesterone with sulphuric acid methyl testosterone with sulphuric acid prednisone with sulphuric acid androsterone with sulphuric acidDiscuss why the target-cell concept is essential forunderstanding hormone function
