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