Across
- 3. accessory pigments that trap light.
- 8. distance between crests of two successive waves of radiant energy.
- 11. the process by which any molecule becomes broken down by light energy.
- 13. the metabolic pathway by which photoautotrophs capture light energy and use it to make sugars from CO2 and water.
Down
- 1. an organic molecule that absorbs light of certain wavelengths.
- 2. the electromagnetic energy of light is organized in packets called_____________.
- 3. organelle of photosynthesis with two outer membranes that enclose a semi-fluid.
- 4. they passed from one molecule of the electron transfer chain to the next. They released bit of their extra energy
- 5. Fixes carbon by attaching CO2 to five carbon RuBP, or ribusebiphosphate.
- 6. in photosynthetic cells, a cluster of pigments and proteins that converts light energy to chemical energy in photosynthesis.
- 7. a chloroplast's inner membrane system. In the first stage of photosynthesis, pigments and enzymes in the membrane function in the formation of ATP and NADPH.
- 9. the main energy carrier between reactions sites in cells.
- 10. coenzyme that accepts electrons and hydrogen ions.
- 12. main photosynthetic pigment in plants, algae, and cyanobacteria.
- 14. the semi-fluid matrix in the chloroplast; site of light-independent photosynthesis reaction.
