Question

Pick the odd one out.

(a) Inertness of the carrier matrix

(b) Matrix should be cheap

(c) Repeated use of enzymes

(d) Matrix should not allow microbial contamination

I had been asked this question in an online quiz.

Origin of the question is Methods of Immobilization in section Immobilized Enzymes Preparation and Kinetics of Enzyme Technology

Answer 1

The correct answer is (c) Repeated use of enzymes

The explanation is: The properties of the carrier matrix are as follows:

• Inertness of the matrix.

• Matrix should be cheap.

• Matrix should not allow microbial contamination.

• Matrix should render enzyme immobile.

• Matrix stability.

• Matrix physical strength.

• Matrix should be easily available.

Repeated use of enzymes is an advantage of immobilized enzymes. Enzyme immobilization means confining an enzyme to a confined space.
