Question
Immobilized enzymes are preferred more over free enzymes in producing biosensors. State true or false
- True
- False
Hint:
Immobilized enzymes are more preferred over free enzymes in producing biosensors because of the following reasons:
• Immobilized enzymes may be re-used ensuring the same catalytic activity for a series of analyses.
• Immobilized enzymes are intrinsically stabled during the immobilization process
• Even if inactivation of enzymes occurs, it is steady and predictable
The correct answer is 'True'.
