Question

Which is the first enzyme to be immobilized by adsorption method?

• A. Protease
• B. Glucose isomerase
• C. Invertase
• D. Amylase

Hint:

Enzyme immobilization is important for industrial applications as it allows enzymes to be reused multiple times, improving the efficiency of various processes.

Answer 1

The Correct Option is C

Invertase was the first enzyme to be immobilized by the adsorption method. Immobilization of enzymes refers to the process of attaching them to solid supports, which allows for repeated use and easier separation from reaction products. Invertase was successfully immobilized on a solid support by adsorption, and this pioneering work opened the door for the use of immobilized enzymes in industrial processes.

(1) Invertase:
- Invertase catalyzes the hydrolysis of sucrose into glucose and fructose. It was the first enzyme to be successfully immobilized through the adsorption method, which laid the foundation for future studies on enzyme immobilization.

(2) Why Other Options Are Incorrect:
- Protease (Option 1) is commonly used in industrial applications but was not the first enzyme immobilized by adsorption.
- Glucose isomerase (Option 2) is used for converting glucose to fructose but was not the first enzyme to be immobilized.
- Amylase (Option 4) is widely used in the food industry but was not the first enzyme immobilized.

Conclusion: Invertase was the first enzyme to be immobilized using the adsorption method, which set the stage for the development of immobilized enzymes for industrial use.
