Across
  1. 4. The process cells use to break down glucose and other molecules to make ATP (energy).
  2. 6. An anaerobic process where pyruvate is turned into alcohol (ethanol) and carbon dioxide while making a small amount of ATP (used by yeast).
  3. 7. An anaerobic process where pyruvate is turned into lactic acid and small amounts of ATP are made (happens in muscle cells during hard exercise).
  4. 9. A process that does require oxygen.
  5. 11. The deeply folded membrane inside the mitochondria where the electron transport chain is located.
  6. 13. A process that does not require oxygen.
  7. 14. The main energy molecule used by cells.
  8. 15. A group of proteins in the inner mitochondrial membrane that use electrons from NADH and FADH₂ to produce lots of ATP.
  9. 16. Another electron carrier that transports electrons to the electron transport chain.
  10. 17. The first step of cellular respiration; glucose is broken into two pyruvate molecules and a small amount of ATP is made.
  11. 18. The process where hydrogen ions (H⁺) flow through ATP synthase to make ATP.
Down
  1. 1. A series of chemical reactions in the mitochondria that break down Acetyl CoA to make CO₂, ATP, NADH, and FADH₂.
  2. 2. A three-carbon molecule produced at the end of glycolysis; it can enter either aerobic respiration or fermentation.
  3. 3. A molecule formed from pyruvate that enters the Krebs cycle during aerobic respiration.
  4. 5. The space between the inner and outer membranes of the mitochondria.
  5. 8. The inner fluid-filled space of the mitochondria where the Krebs cycle happens.
  6. 10. A molecule in the Krebs cycle that joins with Acetyl CoA to start the cycle again.
  7. 12. An electron carrier molecule that stores energy and delivers electrons to the electron transport chain.
