How do you make immobilised enzymes?
Mixing enzymes with alginate and then dropping the mixture in calcium chloride solution
1 of 11
What are advantages of imobilising enzymes?
The enzymes dont contaminate the product and they can be used in continuous flow production
2 of 11
What is the sugar lactose found in?
Milk
3 of 11
What enzyme breaks down lactose?
Lactase
4 of 11
If someone is lactose intolerant, what does this mean?
They lack the enzyme lactase, which means the sugar lactose isn't broken down and gut bacteria ferment it
5 of 11
What are common symptoms of lactose intolerant people?
Abdominal pain, wind and diarrhea
6 of 11
What is lactose broken down into?
Glucose and galactase
7 of 11
How can lactose free milk be produced?
By using immobalised lactase in a continuous flow production
8 of 11
Name the steps in making lactose free milk.
1. Run the milk through a column of immobilised lactase 2. The enzymes convert the lactose into glucose and galactose 3. Only the products emerge through the column, the enzymes stay fixed in the column

What do diabetics use to measure their blood glucose concentration?
Reagent strips with immobilised enzymes
10 of 11
How does this work?
A drop of blood is added to the ***** and the enzymes in the ***** cause it to change colours depending on the concentration of glucose. The colour is then compared to a chart to find out the level of blood sugar
