Across
- 4. a flattened. membrane-bound sac inside a chloroplast where the light-dependent phase of photosynthesis takes place
- 6. describes any chemical process that does not require oxygen
- 8. that portion of photosynthesis that does not require light energy in order to proceed.
- 11. the first phase of cellular respiration, in which glucose is broken down into pyruvate
- 12. a series of compounds that transfer electrons from electron donor substances to electron acceptors. These chains are an important part of both photosynthesis and cellular respiration
- 13. the process by which cells break down glucose or other nutrients to produce usable energy
- 14. describes any chemical process that requires oxygen
Down
- 1. the green pigment of plant cells that is necessary for photosynthesis
- 2. the process whereby plants, algae, and some bacteria form simple sugars from carbon dioxide and water in the presence of light and chlorophyll
- 3. that portion of photosynthesis that requires light energy
- 5. the second phase of aerobic cellular respiration in which pyruvate reacts with enzymes to produce acetyl CoA, carbon dioxide, hydrogen ions, ATP, and electrons; also known as the Krebs cycle
- 7. a small opening on the underside of a leaf that regulates gas exchange
- 9. the anaerobic breakdown of sugars to pyruvate and then to either lactic acid or carbon dioxide and alcohol
- 10. the portion of photosynthesis that uses energy captured during the light-dependent phase to convert carbon dioxide and water into sugars; also known as the light-independent phase
