3. Many enzymes require these inorganic ions for optimal activity.
5. AND KEY The model describing how an enzyme and substrate fit together like a lock and key.
8. A type of inhibitor that binds to a site other than the active site.
9. A factor, besides substrate concentration, that can affect enzyme activity.
13. FIT MODEL The process where an enzyme's active site changes shape to fit the substrate.
16. ACIDS The building blocks of proteins, which most enzymes are made of.
17. Enzymes are biological __________.
20. The general term for a substance that speeds up a chemical reaction.
22. The location on an enzyme where the substrate binds.
23. The molecule that an enzyme acts upon.

1. The breaking down of large molecules into smaller ones.
2. The suffix commonly used to name enzymes.
4. Enzymes are highly ______ for their specific substrates.
6. A type of inhibitor that binds to the active site, blocking the substrate.
7. A condition, like high temperature, that can cause an enzyme to lose its shape and function.
10. The environment in which an enzyme functions best (e.g., acidic or basic).
11. The state of an enzyme after it has catalyzed a reaction, ready to bind another substrate.
12. The overall process that enzymes catalyze.
14. A non-protein helper molecule that assists enzyme function.
15. The study of enzymes.
18. An enzyme that breaks down starch.
