Across
  1. 3. measure of heat energy in food; equivalent to 1000 calories
  2. 4. saclike photosynthetic membranes found in chloroplasts
  3. 8. process that requires oxygen
  4. 11. set of reactions in photosynthesis that use energy from light to produce ATP and NADPH
  5. 13. principal pigment of plants and other photosynthetic organisms
  6. 14. innermost compartment of the mitochondrion
  7. 15. compound used by cells to store and release energy
  8. 17. fluid portion of the chloroplast; outside of the thylakoids
  9. 19. the lightindependent reactions of photosynthesis in which energy from ATP and NADPH is used to build highenergy compounds such as sugar
  10. 23. lightabsorbing molecules used by plants to gather the sun’s energy
  11. 24. organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer
  12. 25. process that does not require oxygen
Down
  1. 1. process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
  2. 2. process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energyrich carbohydrates such as sugars and starches
  3. 5. interconnected, arranged stacks of thylakoids
  4. 6. organism that obtains food by consuming other living things; also called a consumer
  5. 7. an important organic compound in metabolism and is essential to the flow of energy in living cells; formed when ATP ‘loses’ a phosphate group
  6. 9. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
  7. 10. series of electron carrier proteins that shuttle highenergy electrons during ATPgenerating reactions
  8. 12. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
  9. 16. carrier molecule that transfers highenergy electrons from chlorophyll to other molecules
  10. 18. process by which cells release energy in the absence of oxygen
  11. 20. first set of reactions in cellular respiration during which a molecule of glucose is broken into 2 molecules of pyruvic acid
  12. 21. electron carrier involved in glycolysis
  13. 22. second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energyextracting reactions
