Microbes In Human Welfare Question 15

Question: Enzyme immobilisation is:

Options:

A) conversion of an active enzyme into inactive form.

B) providing enzyme with protective covering.

C) changing a soluble enzyme into insoluble state.

D) changing pH so that enzyme is not able to carry out its function.

Show Answer

Answer:

Correct Answer: B

Solution:

Enzyme immobilisation is the confinement of an enzyme to a phase (support/matrix) dissimilar from the one for substrates and products. Inert polymers and inorganic materials are commonly used as carrier matrices.

The inert material can be calcium alginate or sodium.

This can offer increased resistance to changes in conditions like temperature or pH.

There are many benefits of immobilisation, one of which is that the enzymes can be reused - catalysing a similar reaction several times.

Immobilisation allows one to re-use the enzyme for a longer period of time and allows easier separation of the catalyst from the product.

Therefore the correct answer is Option B.
