B2 3 enzymes
Across
1. Building block of lipids.
3. The building blocks of protein.
4. Protein molecule which acts as a biological catalyst. It changes the rate of chemical reactions without being
affect itself at the end of the reaction.
5. Building blocks of lipids.
11. An oil or fat.
12. Washing detergent that contains enzymes.
15. The enzyme made in the salivary glands and the pancreas which speeds up the breakdown of starch into simple
sugars.
16. The reactant for an enzyme.
17. Enzyme which breaks down fats and oils into fatty acids and glycerol.
18. A sugar syrup.
19. Broken down into small molecules by the digestive system.
Down
2. Enzyme which speeds up the breakdown of carbohydrates.
6. A substance which speeds up a chemical reaction. At the end of the reaction the catalyst remains chemically
unchanged.
7. The site on an enzyme where reactants bind.
8. Change the shape of an enzyme so that it can no longer speed up a reaction.
9. Yellowy-green liquid made in the liver and stored in the gall bladder. It is released into the small intestine and
emulsifies fats.
10. An enzyme which breaks down proteins.
13. An enzyme which converts one form of a molecule into another.
14. Breaks down into tiny droplets which will form an emulsion.
