What is the purpose of enzyme immobilisation?
to synthesise new enzymes
to attach or enclose enzymes onto a solid support for reuse and increased stability
to break down enzymes
to separate enzymes from a mixture
|
What is one advantage of immobilising enzymes?
reusability
less prone to technical problems
increased enzyme activity
lower initial costs
|
How does immobilisation affect the stability of enzymes?
immobilisation increases the likelihood of denaturation
immobilised enzymes are less stable
immobilised enzymes are more stable and less likely to denature
immobilisation has no effect on enzyme stability
|
Which enzyme is commonly immobilised to create lactose-free milk?
lipase
amylase
lactase
protease
|
What is one of the main benefits of producing lactose-free milk using immobilised lactase?
it allows for the creation of dairy products for lactose-intolerant individuals
it makes the milk less stable
it increases the lactose content of the milk
it eliminates the need for enzymes in the milk
|
In the given example, what happens to the lactase enzyme after the milk is processed?
it is flushed away with the milk
it is denatured and discarded
it is removed from the column
it remains in the column for further use
|
What is the purpose of running milk through a column containing immobilised lactase?
to remove all enzymes from the milk
to separate lactase from the milk
to increase the lactose content in the milk
to break down lactose in the milk into glucose and galactose
