Across
  1. 6. Energy of motion.
  2. 7. Another name for the Krebs Cycle
  3. 11. Respiration requiring oxygen; occurs in mitochondria and produces a lot of ATP.
  4. 13. Final stage of aerobic respiration; occurs on the cristae, uses NADH and FADH₂, requires oxygen, and produces a lot of ATP and water.
  5. 16. Stored energy (e.g., energy in chemical bonds).
  6. 18. The first stage of respiration; occurs in the cytoplasm, does not require oxygen, and breaks down glucose into pyruvate.
  7. 19. Energy stored in the chemical bonds of compounds like glucose.
  8. 21. The folded inner membrane of the mitochondrion where the electron transport chain occurs.
  9. 22. The breakdown of glucose to release energy (ATP and heat); occurs in 3 stages; needs oxygen.
Down
  1. 1. The inner compartment of the mitochondrion where the Krebs cycle/CAC takes place.
  2. 2. Respiration that occurs without oxygen; produces only small amounts of ATP.
  3. 3. Fluid inside the cell where glycolysis occurs.
  4. 4. An electron carrier molecule produced only in the Krebs cycle/CAC that carries electrons to the electrons transport chain.
  5. 5. A stage of aerobic respiration in the mitochondrial matrix; produces ATP, CO₂, NADH, and FADH₂.
  6. 8. Energy cannot be created or destroyed; it can only change form or be transferred.
  7. 9. The organelle that is the “powerhouse” of the cell where aerobic respiration occurs.
  8. 10. A unit of chemical energy; the energy needed to raise 1 gram of water by 1°C.
  9. 12. A three-carbon molecule that is produced as an output from glucose in glycolysis.
  10. 14. Acts as the final electron acceptor at the end of the ETC; combines with electrons and H+ to make water
  11. 15. The energy currency of the cell; energy is stored in its high-energy phosphate bond.
  12. 17. An electron carrier molecule produced in both glycolysis and the Krebs cycle/CAC; carries high-energy electrons to the electron transport chain.
  13. 20. The ability to perform work.
