  1. 1. Green pigment in chloroplasts that absorbs light energy for photosynthesis.
  2. 4. The sugar molecule produced by photosynthesis and used for energy in cellular respiration.
  3. 6. Series of reactions in the mitochondrial matrix that release CO₂ and generate electron carriers.
  4. 7. The organelle where the Krebs cycle and electron transport chain occur.
  5. 12. The fluid-filled space in chloroplasts where the Calvin cycle takes place.
  6. 15. Cellular respiration that requires oxygen to produce ATP.
  7. 16. Protein complex that uses light energy to produce NADPH.
  8. 18. The main energy currency of the cell produced during cellular respiration.
  9. 19. Protein complex that absorbs light and splits water molecules, releasing oxygen.
  10. 20. The cycle that uses ATP and NADPH to convert CO₂ into glucose.
Down
  1. 2. Reactions that capture sunlight to produce ATP and NADPH.
  2. 3. The first step of cellular respiration that breaks glucose into pyruvate; occurs in the cytoplasm.
  3. 5. Anaerobic process that allows glycolysis to continue by regenerating NAD⁺ when oxygen is absent.
  4. 8. Flattened membrane sacs inside chloroplasts where the light-dependent reactions occur.
  5. 9. The three-carbon molecule produced from glycolysis that enters the mitochondrion for further breakdown.
  6. 10. A chain of proteins in the inner mitochondrial membrane that use electrons to produce ATP.
  7. 11. Electron carrier molecule that transports high-energy electrons to the ETC.
  8. 13. Process of incorporating CO₂ into organic molecules during the Calvin cycle.
  9. 14. Another electron carrier molecule formed during the Krebs cycle.
  10. 17. The organelle in plant cells where photosynthesis occurs.
