  1. 4. ability to do work; it cannot be created or destroyed, only transformed
  2. 6. sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products
  3. 9. catabolic pathway in which organic molecules are broken down to release energy for use by the cell
  4. 11. all of the chemical reactions that occur within the organism
  5. 14. the breakdown of gluclose by enzymes, releasing energy
  6. 16. a metabolic process that requires oxygen
  7. 17. light independent reactions during phase two of photosynthesis in which energy is stored in organic molecules as gluclose
  8. 18. respiration that occurs in certain fungi and bacteria and in human muscle cells during strenuous activity that provides ATP under conditions of oxygen debt
  9. 19. the decomposition or separation of molecules by the action of light
  10. 20. the process by which green plants use sunlight to synthesize food from carbon dioxide and water
  11. 21. metabolic process that does not require oxygen
Down
  1. 1. any colored material found in plant or animal cells
  2. 2. metabolic process in which pyruvate is broken down and electron carrier molecules are used to produce ATP through electron transport
  3. 3. in chloroplasts, one of the stacked, flattened, pigment containing membranes in which light dependent reactions occur
  4. 5. process in which NAD+ is regenerated, allowing cells to maintin glycolysis in the absence of oxygen
  5. 7. enzyme present in plant chloroplasts involved in fixing atmospheric carbon dioxide during photosynthesis
  6. 8. one of the stacks of pigment containing thylakoids in a plant's chloroplast
  7. 10. green pigment present in all green plants and responsible for the absorbtion of light to provide energy for photosynthesis
  8. 12. fluid filled space outside the grana in which light dependent reactions take place
  9. 13. study of the flow and transformation of energy in the universe
  10. 15. energy carrying biological molecule which, when broken down, drives cellular activities
