Question:
Which types of enzyme immobilization method is carrier free:
Which types of enzyme immobilization method is carrier free:
Show Hint
Cross-linking = Hand-in-hand (No carrier needed).
Updated On: May 15, 2026
- Cross linking method of enzyme immobilization
- Entrapment method of enzyme immobilization
- Covalent on support techniques
- Adsorption method of enzyme immobilization
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Enzyme immobilization restricts the movement of enzymes to enhance stability and allow reuse.
Step 2: Meaning
"Carrier-free" means the enzymes are joined together without being attached to a large external support or matrix.
Step 3: Analysis
Adsorption and Covalent methods use a support (carrier). Entrapment uses a matrix. Cross-linking uses bifunctional reagents (like glutaraldehyde) to link enzymes directly to each other.
Step 4: Conclusion
Cross-linking creates a self-immobilized enzyme system that does not require an additional carrier. Final Answer: (A)
