Question
artficial "cell consisting of an aqueous solution enclosed in a selectively permeable An ne is immersed in a beaker containing a different solution, the 'environment membrane is permeable to water and to the simple sugars glucose and fructose but is impermeable to the disaccharide sucrose. a. Is the solution outside the cell (the environment') isotonic, hypotonic, or hypertonic? b. Draw solid arrows in the picture below to indicate the net movement of solutes into and/or out of the cell. Please include labels for each solute particle. Draw a dashed arrow to show the net osmosis, if any. Will the artificial cell gain weight, lose weight, or sta c. d. y the same weight? Eventually, will the two solutions have the same or different solute concentrations? e. "Environment" Cell 0.02 M sucrose 0.03 Msucrose 0.02 M glucose 0.03 M glucose 0.02 M fructoseExplanation / Answer
a)The solution outside the artificial cell is hypertonic.
A hypertonic solution is defiened as a solution where the concentration of solutes is greater outside the cell envelope than inside it.? Therefore in the given example, as the concetration of Sucrose and glucose is higher in the solution of the environment, it is hypertonic.
b) both glucose and fructose move into the artificial cell.
c) given that sucrose cannot pass throug hthe membrane. Hence as the concetration of sucrose is higher in the environment, water moves from the cell into the environment due to osmosis.
d) due to osmosis, water from the artificial cell is lost to the environment. Hence the artificial cell loses weight.
