Across
- 4. Green pigment in plants that absorbs light energy used to carry out photosynthesis, found in the thylakoid of the chloroplast
- 11. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, takes place in plants and animals, happens in 3 processes, steps include gylcolosis, krebs cycle and electron transport chain
- 13. organelle that is the site of ATP (energy) production, (converts glucose into ATP)
- 17. a lower-energy molecule that can be converted into ATP by the addition of a phosphate group, made up of adenosine, ribose and 2 phosphates
- 19. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy, site of the light reactions
- 20. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide, takes place in the mitochondria, produces ATP and NADH
Down
- 1. the breakdown of glucose by enzymes, releasing energy and pyruvate, 1st step in cellular respiration, takes place in the cytoplasm
- 2. process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches steps include: capture light, light dependent reactions, calvin cycle,
- 3. An organelle found only in plant and algae cell, site of photosynthesis occurs
- 5. Respiration that requires oxygen, steps include glycolysis, krebs cycle, electron transport chain, used by our muscles, high energy yield (34 ATP)
- 6. uses the high-energy electrons from the Krebs cycle to convert ADP into ATP, takes place in the mitochondria, produces the most ATP of any of the processes (34 ATP)
- 7. Respiration that does not require oxygen, used by our muscles, low energy yield (2ATP), includes fermentation
- 8. a cluster composed of hundreds of chlorophyll molecules and accessory pigments used to harvest light molecules for photosynthesis
- 9. stacks of thylakoids
- 10. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water (Calvin/Dark reaction)
- 12. reactions reactions of photosynthesis that use energy from light to produce ATP and NADPH, also produces O2
- 14. reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars, also called dark reaction, no light needed, creates NADP+ and ADP, takes place in the stroma
- 15. (adenosine triphosphate) main energy source that cells use for most of their work, made up of adenosine, ribose and 3 phosphates
- 16. electron carrier that provides high-energy electrons for photosynthesis
- 18. one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
