Across
- 2. Produces electron carriers (NADH, FADH₂) for ATP production.
- 4. The energy currency of the cell.
- 6. A protein that speeds up chemical reactions without being consumed.
- 9. The molecule an enzyme acts upon.
- 10. Energy-releasing reactions that break down molecules.
- 11. Produces the most ATP; requires oxygen.
- 12. The first step of glucose breakdown; does not require oxygen.
- 13. Energy-requiring reactions that build complex molecules.
- 14. An inhibitor binds to a site other than the active site, changing enzyme shape.
- 15. A non-protein helper (ion or molecule) required for enzyme activity.
Down
- 1. Loss of an enzyme’s shape, causing it to stop working.
- 3. Anaerobic process that produces small amounts of ATP without oxygen
- 5. Site The region of an enzyme where the substrate binds.
- 7. An inhibitor competes with the substrate for the active site.
- 8. All chemical reactions that occur in a cell.
