6. Enzymes are...
- Specific (they must match the shape of the active site)
- Adaptable (they don't have to match the shape of the active site)
7. The sequence of the amino acids gives the protein its identity and properties...
8. Does an enzyme and a substrate react together or just join?
9. Amylase...
- Catalyses the breakdown of starch
- Removes starch
10. Optimum means the best value for the enzyme to work
11. What are proteins made of?
- Cells
- DNA
- A chain of smaller molecules called amino acids
- Enzymes
12. Proteins are not a chemical group
13. The explanation of how enzymes work is called...
- The lock and key theory - just as a key will only open one lock, an enzyme will only work on one type of substrate
- The enzyme-substrate complex
14. The shapes must fit together for the enzyme to catalyse the breakdown of the substrate
15. Each enzyme has it's own optimum...
- pH and temperature
- pH
- Temperature
16. The place where on an enzyme where a substrate attaches is called...
- The active site
- The lock and key
17. A protein will have...
- No amino acids
- Hundreds or even thousands of amino acids
- One amino acids
- 23 amino acids
18. Which proteins control all the chemical reactions which occur in cells?
- Muscle tissue
- Enzymes
- Hormones
19. What is the substrate for amylase?
- Starch
- Hydrogen peroxide
- Enzyme
20. What will happen if an enzyme is boiled?
- The shape of its active site will change and the substrate will no longer fit
- Nothing
