  1. 1. A unit of heat used to measure the energy your body uses and the energy it receives from food.
  2. 4. A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
  3. 5. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars.
  4. 7. Process that does not require oxygen.
  5. 9. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
  6. 12. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
  7. 14. 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.
  8. 16. Series of proteins embedded in a membrane along which energized electrons are transported.
  9. 17. Is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain.
  10. 18. cycle Second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
  11. 20. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.

  1. 2. Process that requires oxygen.
  2. 3. Conversion of light energy from the sun into chemical energy.
  3. 6. Reactions of photosynthesis that use energy from light to produce ATP and NADPH.
  4. 8. Innermost compartment of the mitochondrion.
  5. 10. The breakdown of glucose by enzymes, releasing energy and pyruvic acid.
  6. 11. A coenzyme that occurs in many living cells and functions as an electron acceptor.
  7. 13. A green pigment found in the chloroplasts of plants, algae, and some bacteria.
  8. 15. Carrier molecule that transfers high-energy electrons from chlorophyll to other molecules.
  9. 19. Main energy source that cells use for most of their work.
