Enzyme Immobilisation Revision

Enzyme immobilisation enhances which of the following properties of an enzyme

• proteinous nature
• specificity
• thermal stability
• catalytic ability

Which of the following explains why the material used to immobilise the enzyme must be inert?

• it ensures that the attachment will be strong
• it ensures that the enzyme activity is not interfered with
• it ensures that the reaction occurs faster than normal
• it prevents the death of the enzyme

Aside from enzymes, what else can be immobilised?

• animal tissues
• animal cells
• animal waste
• animal bones
