Enzymes
Biological catalysts.
1 of 10
Catalysts
Increase the rate of chemical reactions.
2 of 10
Shape of an enzymes
Vital for the enzyme's function. High temperatures change the shape.
3 of 10
Digestive enzymes 1
Produced by specialised cells in glands and in the lining of the gut.
4 of 10
Digestive enzymes 2
The enzymes then pass out of the cells into the gut, where they come into contact with food molecules.
5 of 10
Digestive enzymes 3
The catalyse the breakdown of large molecules into smaller molecules.
6 of 10
Enzymes in the home
Biological detergents may contain protein-digesting and fat-digesting enzymes (proteases and lipases). Biological detergents are more effective at low temperatures than other types of detergents.
7 of 10
Enzymes in industry 1
Proteases are used to 'pre-digest' the protein in some baby foods.
8 of 10
Enzymes in industry 2
Carbohydrases are used to convert starch into sugar syrup.
9 of 10
Enzymes in industry 3
Isomerase is used to convert glucose syrup into fructose syrup, which is much sweeter than glucose and therefore can be used in smaller quantities in slimming foods.
