GCSE Enzymes

4. The molecule that an enzyme acts on
8. A model explaining how an enzyme fits exactly with its substrate
10. A model where the enzyme changes shape slightly to fit the substrate
12. The temperature at which an enzyme works best
13. An enzyme that breaks down fats into fatty acids and glycerol
14. SITE The part of an enzyme where the substrate binds and the reaction occurs
15. When an enzyme loses its shape and can no longer function

1. An enzyme that breaks down starch into sugars
2. Refers to processes related to living organisms
3. An enzyme that breaks down proteins into amino acidsv
5. How fast a chemical reaction happens
6. Describes how an enzyme only works with one particular substrate
7. The pH level at which an enzyme works most efficiently
9. A biological catalyst that speeds up chemical reactions in living cells
11. A substance that increases the rate of a chemical reaction without being used up
