biology
Across
- 4. the breakdown of glucose by enzymes, releasing energy and pyruvate
- 6. process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
- 9. Stacks of thylakoids
- 10. a cluster composed of hundreds of chlorophyll molecules and accessory pigments used to harvest light molecules for photosynthesis
- 11. reactions of photosynthesis in which energy from ATP and NADPH is used to build high energy compounds
- 14. one of the carrier molecules that transfers high energy electrons from chlorophyll to other molecules
- 15. electron carrier that provides high energy electrons for photosynthesis
- 16. organelle that is the site of ATP production
- 17. uses the high energy electrons from the Krebs cycle to convert ADP into ATP
- 18. The fluid of the chloroplast surrounding the thylakoid membrane
- 20. respiration that does not require oxygen
Down
- 1. an organelle found only in plant and algae cell
- 2. green pigment in plants that absorbs light energy used to carry out photosynthesis
- 3. reactions of photosynthesis that use energy from light to produce ATP and NADPH
- 5. Respiration that requires oxygen
- 7. second stage of cellular respiration
- 8. process by which plants and some other organisms use light energy to covert water and carbon dioxide into oxygen and high energy carbohydrates such as sugars and starches
- 12. main energy source that cells use for most of their work
- 13. a lower energy molecule that can be converted into ATP by the addition of a phosphate group
- 19. A flattened membrane sac inside the chloroplast
