  1. 1. dioxide-fourth most abundant gas in the earth's atmosphere.
  2. 4. -an anaerobic respiration that generates methane as the final product of metabolism
  3. 7. - The smallest particle of a substance that has all of the physical and chemical properties of that substance.
  4. 12. -energy is defined as the ability to do work – which, for biology purposes.
  5. 13. -the matrix of the cytoplasm
  6. 15. cycle -a biochemical process by which nutrients are broken down to release energy, which gets stored in the form of ATP and waste products are released.
  7. 16. - a biological catalyst and is almost always a protein
  8. 17. -fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water.
  9. 18. -A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
  10. 19. - Small structures in a cell that are found in the cytoplasm.
  11. 20. - chemical process by which molecules such as glucose are broken down anaerobically.
  12. 23. membrane -separates the interior of the cell from the outside environment.
  13. 24. -a simple molecule composed of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom.
  14. 26. -A process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen
Down
  1. 2. Fermentation -the anaerobic transformation of fructose and glucose (sugars) into ethanol and carbon dioxide.
  2. 3. energy -Energy stored in the bonds of chemical compounds
  3. 5. - any cell or organism that possesses a clearly defined nucleus.
  4. 6. -A type of sugar; the chief source of energy for living organisms.
  5. 8. -The fluid inside a cell but outside the cell's nucleus.
  6. 9. -the act of degrading or the state of being degraded.
  7. 10. -a water-soluble, organic liquid that is produced by breaking down carbohydrates and sugars through the glycolytic pathway (glycolysis).
  8. 11. -without oxygen.
  9. 14. transport -
  10. 21. -A chemical process in which oxygen is used to make energy from carbohydrates (sugars).
  11. 22. - large, complex molecules that play many critical roles in the body.
  12. 25. -A colorless, odorless gas.
