Enzymes and Metabolism

7. A substance participating in a chemical reaction.
10. The specific region of an enzyme where a substrate binds and the catalytic reaction takes place.
11. The substance formed as a result of a chemical reaction.
12. A metabolic process that builds complex molecules from simpler ones, requiring energy input.
13. The reactant on which an enzyme acts, binding to the enzyme's active site.
14. A chemical reaction or process that absorbs energy from its surroundings.

1. A compact, spherical protein structure with a three-dimensional shape.
2. A substance that speeds up a chemical reaction by lowering the activation energy.
3. The change in the shape of an enzyme's active site to better accommodate the substrate.
4. A biological catalyst, usually a protein, that speeds up chemical reactions in living organisms.
5. The breakdown of complex molecules into simpler ones, releasing energy.
6. The minimum energy required for a chemical reaction to occur.
8. A chemical reaction or process that releases energy to its surroundings.
9. The alteration of a protein's shape, leading to loss of its function, often caused by changes in temperature or pH.
