- Here is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. (image 1) The same proteins have been identified in shark rectal gland, marine birds and reptiles (salt glands in nostrils), marine fishes (chloride cells in their gills) and mammals that transport salt in their kidneys. (image 2) When biologists were testing the mechanism of salt excretion in sharks, they used a chemical called ouabain to inhibit the Na+/K+ ATPase to see if there was an effect. Which result would you expect to see with ouabain treatment? A. A decrease in Cl- in the epithelial cells. B. An increase in ADP in the epithelial cells. C. An increase in K+ in the epithelial cells. D. A decrease in Na+ in the epithelial cells.Relate the function of contractile vacuoles to the following experi-mental observations: to expel an amount of fluid equal in volume to its own volume required 4 to 53 minutes for some freshwater unicel-lular eukaryotes, and between 2 and 5 hours for some marine species.Many, but not all, marine fishes are simultaneously both osmoregulators and ionoregulators. Say that a friend caught a fish off of the Cape Cod coast where the seawater has an osmotic pressure of 1,050 mosmol.L-1 and a Na+ concentration of 450 mmol.L-1. Which of the following plasma compositions might reasonably be consistent with your friend's fish being such an osmoregulating and ionoregulating species? A. plasma osmotic pressure = 350 mosmol.L-1; plasma Na+ concentration = 430 mmol.L-1 B. plasma osmotic pressure = 1,050 mosmol.L-1; plasma Na+ concentration = 450 mmol.L-1 C. plasma osmotic pressure = 1,035 mosmol.L-1; plasma Na+ concentration = 170 mmol.L-1 D. plasma osmotic pressure = 355 mosmol.L-1; plasma Na+ concentration = 161 mmol.L-1 E. None of the above answer choices correctly answers the question.

- Physiology of angiotensin II in humans Angiotensin I is enzymatically converted to angiotensin II by ACE. Angiotensinogen II acts on the adrenal cortex to cause the release of storage vesicles containing aldosterone. Angiotensin II is a peptide hormone that is made in advance and stored in vesicles. Physiology of angiotensin II in humans Question 24 options: Angiotensin I is enzymatically converted to angiotensin II by ACE. Angiotensinogen II acts on the adrenal cortex to cause the release of storage vesicles containing aldosterone. Angiotensin II is a peptide hormone that is made in advance and stored in vesicles.The membrane separating compartments A and B of the following chamber is permeable to Cl- ions (gCl = 5) but impermeable to water and K+. The initial concentrations of KCl in compartments A and B, before diffusion has occurred, are presented below. Use this information to answer questions 9-12. Note: Whenever necessary, consider compartment A as the ICF and compartment B as the ECF. KCl = 10 mM A KCl = 150 mM B 9. After equilibrium, the potential of compartment A will be _____mV (include polarity) compared to a reference of 0 mV. Consider compartment B as the outside. A) -70 mV B) 70 mV C) -90 mV D) 90 mV 10. At equilibrium, the flux of Cl- from compartment A to compartment B will be ______ the flux of Cl- from compartment B to compartment A. A) equal to B) less than C) more than 11. Increasing the concentration of [Cl-] in compartment B from 150 mM to 200 mM will ______________. A) make ECl more positive B) make EK more negative C) make ECl more negative D) not change the value of ECl…Transport of biomolecules to tissues takes place through capillary walls by both convection and diffusion. Consider an endothelium in which the gaps between the cells are characterized by the following dimensions: L=1 µm long, h=200 nm high, and W=10 nm in width (the last dimension is the distance between the two cells). The fluid is at 37degC and has the same properties as physiologic saline. Let the average pressure in the capillary be 45 mm Hg and let the pressure in the tissue be 0 mm Hg (ignore osmotic effects). Consider a small solute that has a diffusion coefficient of 1x10-5 cm2/s. Does this solute pass across the endothelium by diffusion or is it primarily carried by flow?
- In the human body, blood vessels can dilate, or increase their radii, in response to various stimuli, so that the volume flow rate of the blood increases. Assume that the pressure at either end of a blood vessel, the length of the vessel, and the viscosity of the blood re- main the same, and determine the factor Ralated/Rpormal by which the radius of a vessel must change in order to double the volume flow rate of the 79. blood through the vessel.What would be the impact on obligatory volume if humans had a medullary concentration gradient extending to 2000 mOsm/L?Identify the mechanism of transport used in this location across the simple cuboidal cell of the proximal convoluted tubule Choose from the following: (A) facilitated diffusion (B) simple diffusion (C) active transport (D) secondary active transport
