  1. 6. The folded membrane inside the mitochondria where the electron transport chain is located.
  2. 7. The main energy molecule cells use.
  3. 11. Happens without oxygen.
  4. 13. A molecule pyruvate turns into before entering the Krebs cycle.
  5. 14. Energy-making without oxygen that produces alcohol and CO₂ (used by yeast).
  6. 15. Another electron-carrying molecule used to help make ATP.
  7. 16. The molecule made at the end of glycolysis.
  8. 17. fermentation: A way cells make energy without oxygen; produces lactic acid (happens in muscles).
Down
  1. 1. A group of proteins that use electrons from NADH and FADH₂ to make lots of ATP.
  2. 2. The small space between the inner and outer membranes of the mitochondria.
  3. 3. The inside fluid of the mitochondria where the Krebs cycle happens.
  4. 4. A molecule in the Krebs cycle that joins with Acetyl CoA to start the cycle again.
  5. 5. The process where hydrogen ions flow through a protein (ATP synthase) to create ATP.
  6. 8. The process cells use to break down food and make energy.
  7. 9. A series of reactions in the mitochondria that makes energy-carrying molecules.
  8. 10. A molecule that carries high-energy electrons to help make ATP.
  9. 11. Happens with oxygen.
  10. 12. The first step of breaking down sugar to make energy; happens in the cytoplasm.
