enzyme puzzle

2. / enzyme lacked by lactose intolerant people
4. / rate of reaction as pH exceeds the optimum level
6. / enzymes that can be used many times, resulting in cost saving
7. / region on the surface of the enzyme to which the substrate binds and which catalyses the reaction
9. / induced by the substrate approaching the enzyme
12. / The substrate and active site match each other structurally and chemically
13. / reactant in a biochemical reaction
15. / change in the conformation of the protein
16. / globular protein that acts as a biological catalyst (increases the rate of reaction by lowering the activation energy threshold)
17. / enzymes attached to a material so that their movement is restricted
19. / affected by the substrate concentration

1. / the substrate and active site happen to be correctly aligned to allow binding to take place
3. / Minimum energy required for the reactants to possess in order to undergo a chemical reaction
5. / contain proteases and lipases to break down stains
8. / coming together of a substrate and an active site
10. / can cause denaturation as vibrations in the molecule break the intermolecular bonds or interactions
11. / increase in rate of reaction caused by a globular protein
14. / enzyme that catalyses the conversion of hydrogen peroxide into water and oxygen
18. / used in cheese production
