Across
  1. 2. photosynthetic membranes found in chloroplasts
  2. 6. 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
  3. 8. (adenosine triphosphate)--compound used by cells to store and release energy
  4. 9. 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 energy-rich carbohydrates such as sugars and starches
  5. 10. reactions set of reactions in photosynthesis that use energy from light to produce ATP and NADPH
  6. 13. portion of the chloroplast; outside of the thylakoids
  7. 14. respiration process that releases energy from food in the presence of oxygen
  8. 15. simple sugar molecule
  9. 17. cycle second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
  10. 19. organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
  11. 20. reactions set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle
  12. 22. process that does not require oxygen
  13. 23. transport chain series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
  14. 24. of heat energy in food; equivalent to 1000 calories
Down
  1. 1. a complex carbohydrate made up of many monosaccharides
  2. 3. fermentation process by which cells release energy in the absence of oxygen; produces carbon dioxide and alcohol
  3. 4. process that requires oxygen
  4. 5. compound made up of carbon, hydrogen, and oxygen atoms; type of nutrient that is the major source of energy for the body
  5. 7. that obtains food by consuming other living things; also called a consumer
  6. 11. found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
  7. 12. to do work
  8. 16. Acid Fermentation process by which cells release energy in the absence of oxygen; produces lactic acid
  9. 18. first set of reactions in cellular respiration during which one molecule of glucose (a 6 carbon compound) is transformed into 2 molecules of pyruvic acid (a 3 carbon compound)
  10. 21. light-absorbing molecules used by plants to gather the sun’s energy
