In the Process of Dialysis, a Special Semipermeable Membrane Allows

question 62

Multiple Choice

In the process of dialysis, a special semipermeable membrane allows both small molecules and water to pass through, but not large protein molecules. These membranes are used to separate these small molecules and ions from much larger proteins. If a mixture of proteins and small molecules were separated from pure water by a dialysis membrane as shown in the figure, which way would the molecules flow?

• A) Both water and small molecules would pass through into the pure water.
• B) Only the proteins would pass through into the pure water.
• C) Water would enter the solution while small molecules would pass through into the pure water.
• D) Only small molecules would pass through the membrane, water and proteins would not.
• E) Only water would pass through the membrane into the solution.
