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

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
