  1. 5. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy, site of the light reactions
  2. 8. Respiration that does not require oxygen
  3. 9. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water (Calvin/Dark reaction)
  4. 10. organelle that is the site of ATP (energy) production
  5. 11. 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. 12. organism that obtains energy from the foods it consumes; also called a consumer
  7. 14. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide, takes place in the mitochondria, produces ATP and NADH
  8. 15. A process used by yeast cells and some bacteria to produce carbon dioxide and ethyl alcohol
  9. 17. Produced by fermentation and oxidation of natural carbohydrates is called vinegar
  10. 18. a cluster composed of hundreds of chlorophyll molecules and accessory pigments used to harvest light molecules for photosynthesis
  11. 19. An organelle found only in plant and algae cell, site of photosynthesis occurs
  12. 20. Respiration that requires oxygen
Down
  1. 1. The conversion of pyruvate to lactate with no release of carbon dioxide
  2. 2. 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
  3. 3. Process by which cells release energy in the absence of oxygen
  4. 4. reactions of photosynthesis that use energy from light to produce ATP and NADPH, also produces O2
  5. 6. Green pigment in plants that absorbs light energy used to carry out photosynthesis, found in the thylakoid of the chloroplast
  6. 7. The movement of phosphorus atoms from rocks through the biosphere and hydrosphere and back to rocks.
  7. 13. 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)
  8. 15. Organisms that make their own food
  9. 16. the passage of energy through the components of the ecosystem
