  1. 3. The most abundant enzyme on Earth. An enzyme that fixes CO2 to RuBP in the Calvin cycle.
  2. 5. (Two words) Coloured chemicals within the photosystem arrays that absorb light at different wavelengths and then pass energy onto chlorophyll a
  3. 7. The production of energetic electrons in reaction centers through the absorption of light.
  4. 10. The molecule that reacts with CO2 during carbon fixation.
  5. 11. The splitting of water.
  6. 12. (Two words) A graph that profiles the relative effectiveness of different wavelengths of radiation in driving a particular process (Photosynthesis).
  7. 14. (Word and number)The first photosystem in the light-dependent reactions - it uses electrons from photolysis, and produces ATP.
  8. 15. The organelles that capture the light energy from sunlight and convert it into chemical energy in a process called photosynthesis
  9. 17. (Two words) Factors that affect the rate of photosynthesis: temperature, light intensity, carbon dioxide concentration
  10. 19. (Two words) The incorporation of inorganic CO2 into an organic molecule.
  11. 21. (Word-number-word)Intermediate compound produced during the Calvin cycle in the light-independent stage of photosynthesis.
  12. 22. The chemical medium between the inner chloroplast membrane and the thylakoid membrane.
  13. 23. The membrane that is the site of photosynthesis.
Down
  1. 1. the production of ATP using the energy of sunlight.
  2. 2. (Two words) the name of the reactions within photosynthesis that use light to generate ATP and reduced NADP for the second phase of photosynthesis..
  3. 4. A technique that is used to separate the components of a mixture based on the tendency of each component to travel or be drawn across the surface of another material.
  4. 6. (Two words) Coloured chemicals that absorb light energy and use it to carry out photosynthesis. Contained in thylakoid membranes in chloroplast. Examples are chlorophyll a, chlorophyll b, carotenoids, and xanthophylls.
  5. 8. (Two words) A transmembrane protein complex in the thylakoid membrane containing chlorophyll a whose electrons absorb light energy and become high energy electrons which are passed to the primary electron acceptor in the Electron Transport Chain (ETC), thus beginning the process of photosynthesis.
  6. 9. (Two words) A graph plotting the range of a pigment's ability to absorb various wavelengths of light.
  7. 13. A numerical value that can be used to identify photosynthetic pigment. The value is created by using measurements from chromatography in this equation: Distance travelled by substance / distance travelled by solvent
  8. 16. (Two words)an intermediate in the Calvin cycle, also known as glyceraldehyde-3-phosphate.
  9. 18. (Two words) The use of ATP and reduced NADP in the stroma to regenerate RuBP and generate carbohydrates in the light independent stage of photosynthesis.
  10. 20. The process of making ATP using the energy stored in a proton gradient.
