- What effect might a change in extracellular osmolarity have on the movement of water across cell membranes (you can assume that plasma and interstitial fluid osmolarities are the same)?Calculate the osmolarity of a 3% NaCl solution. Is this solution hypotonic OR hypertonic?How is osmolarity the same inside and outside of the cell if the ions are different on both sides?
- [#3] (9 pts) Fill in the table by using the words "hypo", "iso", ar "hyper" in the blanks to describe the relative osmolarity of the two solutions given as pairs (horizontally). Draw an arrow (left, right, or double-headed) to indicate the net movement of water if the twa solutions of the pair were separated by a selectively permeable membrane that allows water to low but prevents ions from crossing the membrane. Solution pair# Solution A of pair draw an arrow in this column for each nair indicating net movement of water due to osmosis Solution Bof pair salty water from road salt used to melt ice tree rools along the street Pair #1 Osmotie osmotic pure distilled water your eye Pair #2 Osmotie osmotic red blood cells blood plasma Pair #3 Osmotic osmoticRed blood cells with an internal osmolarity of 300 mOsM/L are placed in a solution containing 300mOsm/L glucose. Which of the following must be TRUE about the solution? a) the solution is isosmotic b) the solution is isotonic c) both A and B d) Neither A nor Bwhat is the amount of solute in a solution in terms of osmolarity and tonicity?
- Assume a cell has an osmolarity of 10 mM. What will happen to that cell (swell, shrink, or stay the same) if it is placed in a solution of: a) 5 mM glucose b) 10 mM glucose c) 10 mM NaClDefine osmosis and solve simple problems involving osmosis; for example, predict whether cells will swell or shrink under various osmotic conditions.A solution may have the same osmolarity as normal body fluids yet it may not be isotonic. Explain why.
- Calculate the osmolarity of the following solution: Dextrose (MW = 180) 8% %3D Sodium chloride (MW = 58.5) 0.45% Potassium chloride (MW = 74.5) 35mEq Sterile water qs ad 1000mla) 5.5% glucose and 0.9% NaCl have the same osmolarity. What is the osmolarity of these solutions? Please show your work. b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution. (b) Identify the osmolarity of the apple.
