Across
  1. 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.
  2. 6. A complex set of chemical reactions involving an energy transformation where potential chemical energy in the bonds of "food" molecules is released and partially captured in the bonds of adenosine triphosphate (ATP) molecules; creating energy or ATP from glucose and oxygen
  3. 7. An organism that obtains organic food molecules by eating other organisms or substances derived from them.
  4. 11. Membranes in chloroplasts that are arranged in flattened sacs and make up the grana, the site of the light reactions
  5. 13. A molecule used to store energy temporarily in organisms. The molecule is broken down to release energy to drive metabolic processes; 3 phosphate groups, 1 ribose, 1 adenine---hydrolyzed to make ADP and release energy
  6. 14. An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
  7. 16. a process used by plants and other autotrophs to capture light and 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.
  8. 18. An organelle found in plant and algae cells where photosynthesis occurs
  9. 20. A biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP and NADPH.
  10. 21. The steps in photosynthesis that occur on the thylakoid membranes of the chloroplast and that convert solar energy to the chemical energy of ATP and NADPH, evolving oxygen in the process.
  11. 24. (with oxygen) glucose is completely oxidized to carbon dioxide and water the total oxidation allows for the maximum amount of energy to be released.
Down
  1. 1. a type of fermentation; the process used by yeast cells and some bacteria to produce carbon dioxide and ethyl alcohol
  2. 2. acetyl groups from the pyruvic acids (produced by glycolysis) are broken down to carbon dioxide, accompanied by the formation of ATP and electron carriers; occurs in the matrix of mitochondria.
  3. 3. Fluid within a chloroplast that contains enzymes involved in the synthesis of carbohydrates during photosynthesis.
  4. 5. A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP
  5. 8. Green pigment in plants that absorbs light energy used to carry out photosynthesis.
  6. 9. A process in chloroplasts and mitochondria in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP
  7. 10. a type of fermentation; the chemical breakdown of carbohydrates that produces lactic acid as the main end product, can cause muscle soreness
  8. 12. the three-carbon compound that is produced during glycolysis and needed for both the aerobic and anaerobic pathways
  9. 15. An organism that makes its own food
  10. 17. 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
  11. 19. A part of light-dependent reactions that contains a light-harvesting complex and a reaction-center complex.
  12. 22. (without oxygen) Break down of carbohydrates without oxygen where less energy is produced
  13. 23. An energy-carrying coenzyme produced by glycolysis and the Krebs cycle and carries energy to the electron transport chain, where it is stored in ATP.
