Question

What is the primary role of calcium alginate in enzyme immobilization?

• A. Provides covalent attachment to enzymes
• B. Maintains high substrate concentration
• C. Forms a gel matrix for entrapment
• D. Increases enzyme turnover number

Hint:

For enzyme immobilization, consider materials that create a stable matrix to hold enzymes without compromising activity.

Answer 1

The Correct Option is C

Calcium alginate is widely used in enzyme immobilization due to its ability to form a gel matrix, which physically entraps the enzymes. This matrix helps maintain enzyme activity while making them easier to handle and reuse. While it can indirectly affect substrate concentration and enzyme turnover, its main role is as a supportive structure for enzyme entrapment.
