Question

Immobilisation protects an enzyme against

• A. High temperature
• B. Low temperature
• C. Amylases
• D. Proteases

Answer 1

The correct option is D Proteases

Immobilization of enzymes is the process of fixing enzyme to or enclosing it in a solid support so as to protect it from deactivation and attack from proteases, maintain enzyme purity, ability to recover it after reaction and perform a continuous reaction. Since the reaction is continuous, it requires minimum reaction time and continuous use of enzyme is possible. The enzymes can be reused since it maintains the enzyme purity.

Thus the correct option is D.
