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