Across
  1. 3. stacks of thylakoids
  2. 5. light-absorbing colored molecule, such as chlorophyll or carotenoid, in the thylakoid membranes of chloroplasts
  3. 7. the ability to do work
  4. 9. the catabolic pathway in which organic molecules are broken down to release energy for use by the cell
  5. 10. energy-carrying biological molecule, which, when broken down, drives cellular activities
  6. 13. a metabolic process that requires oxygen
  7. 15. process in which NAD is regenerated, allowing cells to maintain glycolysis in the absence of oxygen
  8. 16. organism that captures energy from sunlight or inorganic substances to produce its own food; provides the foundation of the food supply for other organisms; also called a producer
  9. 17. series of reactions in which pyruvate is broken down into carbon dioxide inside the mitochondria of cells; also called the tricarboxylic acid cycle and the citric acid cycle
  10. 19. breaking larger molecules down to smaller molecules
  11. 21. all of the chemical reactions that occur within a cell
  12. 22. in photosynthesis, the major electron carrier involved in electron transport
  13. 23. enzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the Calvin cycle
Down
  1. 1. metabolic process that does not require oxygen
  2. 2. organism that cannot make its own food and gets its nutrients and energy requirements by feeding on other organisms; also called a consumer
  3. 4. metabolic process in which pyruvate is broken down and electron-carrier molecules are used to produce ATP through electron transport
  4. 6. in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occur
  5. 8. an anaerobic process; the first stage of cellular respiration, in which glucose is broken down into two molecules of pyruvate
  6. 11. the study of the flow and transformation of energy in the universe
  7. 12. light-independent reactions during phase two of photosynthesis in which energy is stored in organic molecules as glucose
  8. 14. building larger molecules using smaller molecules
  9. 18. fluid-filled space outside the grana where the light-independent reactions of photosynthesis take place
  10. 20. the anabolic process in which light energy from the Sun is converted to chemical energy
