Across
  1. 6. 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
  2. 11. Process that does not require oxygen
  3. 12. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions; also called the Citric-Acid Cycle
  4. 14. A metabolic process that breaks down carbohydrates and sugars through a series of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of ATP
  5. 15. (adenosine triphosphate) main energy source that cells use for most of their work
  6. 17. Process by which cells release energy in the absence of oxygen
  7. 19. Process that requires oxygen
  8. 20. organelles that convert chemical energy stored in food into compounds more convenient
Down
  1. 1. A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
  2. 2. reactions of photosynthesis that use energy from light to produce ATP and NADPH
  3. 3. (Adenosine Diphosphate) The compound that remains when a phosphate group is removed from ATP, releasing energy
  4. 4. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
  5. 5. series of electron carrier proteins that shuttle (move) high-energy electrons during ATP-generating reactions
  6. 7. A green pigment found in the chloroplasts of plants, algae, and some bacteria
  7. 8. Process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates
  8. 9. Conversion of light energy from the sun into chemical energy.
  9. 10. the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.
  10. 13. Molecules that absorb, reflect, or transmit light.
  11. 16. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
  12. 18. An organelle found in plant and algae cells where photosynthesis occurs
