Question

The restriction of enzyme mobility in a fixed space is known as ___________

(a) enzyme immobilization

(b) enzyme inhibition

(c) enzyme kinetics

(d) biosensor

I have been asked this question at a job interview.

The doubt is from Methods of Immobilization in chapter Immobilized Enzymes Preparation and Kinetics of Enzyme Technology

Answer 1

Correct choice is (a) enzyme immobilization

Explanation: The restriction of enzyme solubility in a fixed space is known as enzyme immobilization. Immobilization does not always mean immobile; it means confining an enzyme to a confined space. This may be achieved by fixing the enzyme, to or within, some other material. Enzyme kinetics is referred to as study of rates of chemical reactions that are catalyzed by enzymes. Biosensors are analytical devices which convert biological response into an electrical signal. Enzyme inhibition is referred to as the process in which the rate of an enzyme catalyzed reaction is reduced.
