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