Question

The membrane used for dialysis is made of:

• A. Polyethylene
• B. Cellulose
• C. Polyvinyl Chloride
• D. Chitin

Hint:

Cellulose is used in dialysis membranes due to its selective permeability to small solutes.

Answer 1

The Correct Option is B

The dialysis membrane is typically made of cellulose or synthetic polymers that allow for the selective diffusion of small molecules, such as waste products, while retaining larger molecules like proteins. Polyethylene, polyvinyl chloride, and chitin are not commonly used in dialysis membranes.
Conclusion: The correct material for dialysis membranes is cellulose.
