An osmotic semipermeable membrane that allows
only water to pass separates two compartments,
A and B. Compartment A contains 0.9% NaCl,
and compartment B contains 3% glycerol, C3H8O3.
(a) In which compartment will the level of solution
rise?
(b) Which compartment has the higher osmotic
pressure (if either)?
The most cation that found in extacellular fluid is
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
