Enzymes

3. The loss of an enzyme's shape and function due to extreme changes in temperature or pH.
5. A model that describes how the active site of an enzyme adjusts its shape to accommodate the substrate.
7. Organic molecules that act as cofactors for certain enzymes, often derived from vitamins.
9. Chemical transformation facilitated by enzymes, reducing the activation energy required for the reaction to occur.
10. A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.
12. The process by which an enzyme's activity is reduced or blocked by another molecule.
15. The specific molecule upon which an enzyme acts during a chemical reaction.
16. Reactions only progress in one direction, forming products from reactants.
19. When an inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's conformation.
20. A substance that increases the rate of a chemical reaction without being consumed in the process.
21. Measures the speed of enzyme-catalyzed reactions.
22. When a molecule similar in structure to the substrate competes with the substrate for the enzyme's active site.

1. A model that illustrates the specificity of enzyme-substrate interactions, where the active site of the enzyme is complementary in shape to the substrate.
2. Reaction can proceed in both forward and reverse directions.
4. When a molecule competes with the substrate for binding to the enzyme's active site.
6. Chemical reactions within living organisms regulated by enzymes.
8. An enzyme functions at its maximum efficiency, typically under specific conditions such as pH and temperature.
11. Influences the rate of enzymatic reactions
13. The region of the enzyme where the substrate binds and the catalytic reaction takes place.
14. The energy required to start a chemical reaction, which enzymes lower.
17. The molecules formed as a result of an enzyme-catalyzed reaction.
18. Inorganic molecules or ions that assist enzymes in catalyzing reactions.
