Each question carries 20 marks. Immobilised enzymes are widely used commercially — they can be immobilised in three ways: Since immobilized enzymes can be recovered from reaction mixture and can be made available for reuse again, so, they are preferred to free enzymes.

They are specific in their action and are therefore less likely to produce unwanted by-products. This is why enzymes are immobilised onto a surface or tool The support or matrix on which the enzymes are immobilized allows the exchange of medium containing substrate or effector or inhibitor molecules.
