  1. 3. The portion of photosynthesis that uses energy captured during the light-dependent phase to convert carbon dioxide and water into sugars; also known as the light-independent phase.
  2. 5. the green pigment of plant cells that is necessary for photosynthesis.
  3. 6. the anaerobic breakdown of sugars to pyruvate and then to either lactic acid or carbon dioxide.
  4. 9. any chemical process that does not require oxygen.
  5. 13. the second phase of aerobic cellular respiration in which pyruvate reacts with enzymes to produce acetyl CoA carbon dioxide, hydrogen ions, ATP, and electrons; called the Krebs cycle.
  6. 16. A random change in the sequence of bases in a DNA molecule.
  7. 19. a flattened, membrane-bound sac inside a chloroplast where the light-dependent phase of photosynthesis takes place.
  8. 21. the __________ phase, the portion of photosynthesis that requires light energy.
  9. 22. The phase of metabolism that breaks down molecules and releases energy.
  10. 23. The molecule produced when ATP is used for energy.
  11. 24. The sum of all the chemical processes needed within a cell to maintain life.
  12. 25. The process by which a ribosome builds a protein that is based on the sequence of codons in an mRNA molecule.
  13. 26. The phase of metabolism that builds molecules and stores energy.

  1. 1. The process by which a particular segment of DNA is copied into RNA.
  2. 2. the material within a chloroplast that surrounds the thylakoids.
  3. 4. the first phase of cellular respiration, which glucose is broken down into pyruvate.
  4. 7. A molecule used within all cells for temporary energy storage.
  5. 8. the __________ phase, the portion of photosynthesis that does not require light energy in order to proceed. But the light-independent phase does require the products of the light-dependent phase; therefore, neither phase occurs during darkness. AKA Clavin cycle.
  6. 10. the process by which cells break down glucose or other nutrients to produce usable energy.
  7. 11. The single-stranded genetic information molecule, copied from DNA, whose pain function is, in conjunction with ribosomes, to build protein molecules.
  8. 12. THe process by which a strand of DNA is copied to produce an identical strand.
  9. 14. A pair of complementary nitrogenous bases that comet the two halves of a DNA molecule.
  10. 15. The set of three bases on a molecule of tRNA that corresponds to a complimentary codon on an mRNA molecule.
  11. 17. a set of three bases in an RNA strand that together code for a specific amino acid.
  12. 18. the process whereby plants, algae, and some bacteria form simple sugars from carbon dioxide and water in the presence of light and chlorophyll.
  13. 20. The double-stranded molecule used by most cells for storing genetic information.
