Enzymes can be immobilised and then used in bioprocessing. a) What is meant by immobilisation?
b) Name a substance that is used to immobilise enzymes.
c) Give one application of a named immobilised enzyme. In your answer, refer to substrate, enzyme and product.

1. Immobilisation is to make immobile or immovable; fix in place. to prevent the use, activity, or movement of: The hurricane immobilized the airlines. to deprive of the capacity for mobilization: The troops were immobilized by the enemy.

2.An immobilized enzyme is, therefore, attached to an inert, organic, or inorganic or insoluble material, such as calcium alginate or silica. Furthermore, the attachment of an enzyme to a solid support can increase its resistance to various environmental changes such as pH or temperature

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
