Textbook Question
Chapter 5, Problem 13TYK
Cells lining kidney tubules function in the reabsorption of water from urine. In response to chemical signals, they reversibly insert additional aquaporins into their plasma membranes. In which of these situations would your tubule cells have the most aquaporins: after a long run on a hot day, right after a large meal, or after drinking a large bottle of water? Explain.

Two solutions are separated by a semipermeable membrane that is permeable only to water. The two solutions are: Solution A = 150 mM KCl Solution B = 150 mM Angiotensin (a 7 amino acid polypeptide) Which of the following would best explain the net movement in this situation?
- water will move from the KCl side to Angiotensin side
- water will move from Angiotensin side to KCl side
- The Cl- ion will move to the angiotensin side until there is 75 mM Cl- on each side
- Since Angiotensin is not an ion, it can move through the membrane
- There is no net water movement as the concentrations are the same on both sides
The mammalian kidney contains an immense network of nephrons that functions to conserve water by producing urine that is hyperosmotic compared to other body fluids.
Explain how the transport epithelia of the nephron and collecting duct are able to use transport mechanisms to process the filtrate as it moves through the vessels and produce a hyperosmotic filtrate.
A fraternity hazing practice involves pressuring freshmen to drink large quantities of pure water in a very short time period. Explain in a few sentences why this is dangerous, given what you know about osmotic pressure and cells.
