Aldosterone is a steroid hormone that freely enters the target cells to act within the cell. Epinephrine is a polar monoamine (amino acid) hormone that interacts with receptors on the cell's surface. What accounts for this difference? [Select any/all that apply.] Steroids are charged and hydrophilic, so aldosterone passed through a transport protein. Steroids are hydrophobic so aldosterone passed through the membrane by simple diffusion. Epinepherine (amino acid) hormone is hydrophilic, so it cannot diffuse through the phospholipid bilayer. Epinepherine (amino acid) hormone could diffuse through the phospholipid bilayer but it is attracted to the receptor protein.

The immediate effect of ADH on the renal tubules of frogs and mice is the same, yet when ADH is secreted, frogs produce urine that is approximately isosmotic to their blood plasma, whereas mice produce urine far more concentrated than their blood plasma. Explain this difference in terms of the factors affecting osmosis in the kidneys of frogs and mice.
Ion transporters are “linked” together—not physi-cally, but as a consequence of their actions. For example,cells can raise their intracellular pH, when it becomes tooacidic, by exchanging external Na+ for internal H+, usinga Na+–H+ antiporter. The change in internal Na+ is thenredressed using the Na+-K+ pump.A. Can these two transporters, operating together,normalize both the H+ and the Na+ concentrations insidethe cell?B. Does the linked action of these two pumps causeimbalances in either the K+ concentration or the mem-brane potential? Why or why not?
Renal tubule cells acidify the urine and parietal cells acidify the stomach contents. In each case (a) which intracellular enzyme is key, and (b) blood concentration of which ion increases?
Renal tubule cells in the kidney medulla are constantly exposed to high extracellular osmolirity. How do they maintain normal cell volume?
What effect does an increase in antidiuretic hormone (ADH) have on the volume of extracellular fluid (ECF)? a. ECF decreases when antidiuretic hormone (ADH) is present. b. ECF increases initially, then decreases when antidiuretic hormone (ADH) is present. c. ECF increases when antidiuretic hormone (ADH) is present. d. Antidiuretic hormone (ADH) has no effect on ECF.
When the body becomes dehydrated, the posterior pituitary gland secretes vasopressin which signals the kidney tubules to retain water leading to infrequent urination. Which type of cellular communication is mediated by vasopressin?
With regard to fluid movement between body fluid compartments, what effect does oral/parenteral administration of a hypotonic NaCl solution (0.45% NaCl, 145 mOsm/kg) have on the volume & osmolality of the extracellular fluid compartment (ECF), and on the volume & osmolality of the intracellular fluid compartment (ICF)? Clearly explain your reasoning
The cell membranes of mammalian red blood cells are permeableto urea. If red blood cells are dropped into a solution of urea thatis identical in osmotic pressure (isosmotic) to the cytoplasm ofthe cells, although the cells do not swell and burst as quickly aswhen they are dropped simply into pure water, they eventuallyswell and burst. Explain. Also discuss how you would designa solution into which red cells could be placed without everswelling. (Hint: Think about whether urea will stay on theoutside of the cells and the implications for osmotic pressures.)
In the management of DKA, why would potassium be added to the maintenance fluids even if potassium levels are normal or high? Question 66 options: a) Potassium shifts from the extracellular fluid to the intracellular fluid when acidosis corrects b) Insulin promotes renal potassium loss c) Osmotic diuresis may continue to deplete extracellular fluid potassium levels d) Maintenance fluids will dilute potassium levels in the extracellular fluid
Sodium-Potassium Pumps (N+/K+ ATPase) are fundamental to your body’s physiological function. What is the connection/importance of this phenomenon in the urinary system with examples?
In IBD1, if 20 mg of a drug is ultimately excreted unchanged into urine, the amount of the drug excreted unchanged into urine after 2 half-lives is _____ mg. Round the answer into the nearest integer.
"Transporters saturate at high concentrations of the transported molecule when all their binding sites are occupied; channels, on the other hand, do not bind the ions they transport and thus the flux of ions through a channel does not saturate." is true or false.
