You generated liposomes with phospholipid and cholesterol from a
solution containing NaCl, glucose, and glycerol. You precipitated
the liposomes and transferred them into a solution containing
distilled water. Would this liposome generate a membrane
potential?
YES OR NO?
Homework Answers
Would this liposome generate a membrane potential?
Yes
Differences in the concentrations of ions on opposite sides of a cellular membrane result a voltage that is called the membrane potential.

q16
An aqueous solution containing glucose has a vapor pressure of 19.9 torr at 25°C. What would be the vapor pressure of this solution at 45°C? The vapor pressure of pure water is 23.8 torr at 25°C and 71.9 torr at 45°C. Vapor pressure torr If the glucose in the solution were substituted with an equivalent amount (moles) of NaCl, what would be the vapor pressure at 45°C? Vapor pressure torr

1) Suppose you made an intravenous solution, intended to be isoosmotic to red blood cells (i.e., 300 mOsm). You add 5 grams of NaCl to 800 ml of distilled water. Will this solution be isoosmotic to cells? if not, what will happen to the cells? (Will they take in water or lose water?) How would you make 500ml of a 5% NaCl solution? You dissolve 20 grams of glucose into water to give a solution whose final volume is exactly...
