Across
  1. 1. - A high-energy electron carrier produced during glycolysis and the Krebs cycle.
  2. 4. - An electron carrier produced in the Krebs cycle, similar to NADH.
  3. 7. - The organelle where aerobic respiration occurs.
  4. 10. - The first stage of cellular respiration that occurs in the cytoplasm.
  5. 12. - The loss of electrons in a chemical reaction, often associated with the release of energy.
  6. 13. - The end product of glycolysis.
  7. 14. Dioxide - A byproduct of the Krebs cycle and cellular respiration overall.
  8. 15. - A byproduct of the electron transport chain when oxygen binds with hydrogen ions.
  9. 16. - The final electron acceptor in the electron transport chain.
Down
  1. 2. - Type of respiration that occurs in the absence of oxygen.
  2. 3. - The cycle also known as the citric acid cycle.
  3. 5. - The area inside the mitochondria where the Krebs cycle takes place.
  4. 6. - The six-carbon sugar molecule that starts the process of cellular respiration.
  5. 8. - The main energy carrier produced by cellular respiration.
  6. 9. - Part of the "electron transport chain" stage in cellular respiration.
  7. 11. - A process that allows glycolysis to continue without oxygen.
