  1. 4. Green pigment in plants that absorbs light energy used to carry out photosynthesis, found in the thylakoid of the chloroplast
  2. 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
  3. 13. organelle that is the site of ATP (energy) production, (converts glucose into ATP)
  4. 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
  5. 19. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy, site of the light reactions
  6. 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. 1. the breakdown of glucose by enzymes, releasing energy and pyruvate, 1st step in cellular respiration, takes place in the cytoplasm
  2. 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. 3. An organelle found only in plant and algae cell, site of photosynthesis occurs
  4. 5. Respiration that requires oxygen, steps include glycolysis, krebs cycle, electron transport chain, used by our muscles, high energy yield (34 ATP)
  5. 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)
  6. 7. Respiration that does not require oxygen, used by our muscles, low energy yield (2ATP), includes fermentation
  7. 8. a cluster composed of hundreds of chlorophyll molecules and accessory pigments used to harvest light molecules for photosynthesis
  8. 9. stacks of thylakoids
  9. 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)
  10. 12. reactions reactions of photosynthesis that use energy from light to produce ATP and NADPH, also produces O2
  11. 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
  12. 15. (adenosine triphosphate) main energy source that cells use for most of their work, made up of adenosine, ribose and 3 phosphates
  13. 16. electron carrier that provides high-energy electrons for photosynthesis
  14. 18. one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
