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