The flashcards below were created by user aphy101 on FreezingBlue Flashcards. What would you like to do?


  1. What enters the electron transport chain?
    Hydrogen, electrons, and oxygen
  2. What are the products of ETC? (what does it release?)
    water and ATP
  3. Is the electron transport chain aerobic or anaerobic?
    Aerobic
  4. How does the O2 work as the final electron receptor?
    It binds with hydrogen atoms to make water (and when the oxygen is gone, the aerobic reactions can't continue and the cell dies)
  5. Briefly summarize what happens during lactic acid (fermentation) pathway.
    The fermentation pathway gives the lactic acid oxygen to turn into pyruvic acid so that it can go about its normal cycle
  6. Why is the pathway so important (what would happen if you did not have it available)?
    If you don't have the oxygen, the aerobic reactions stop and the cell dies
  7. How is NAD involved in the lactic acid pathway?
    It is a carrier that gives its electrons and hydrogens back to the pyruvic acid
  8. Genetic material located in the nucleus that holds the instructions for a cell to synthesize a particular protein
    Deoxyribonucleic Acid (DNA)
  9. What is the correspondence between a unit of DNA information and an amino acid?
    Genetic Code
  10. A sequence of DNA that contains the instructions for a cell to synthesize a particular protein
    Gene
  11. What is the total set of genetic instructions in a cell, including the genes?
    Genome
  12. The shape of the double-stranded DNA molecule as it twists is known as what?
    Double Helix
  13. In DNA strands, A always binds to T, G always binds to C. These are known as what?
    Complementary Base Pairs
  14. What is the process that creates an exact copy of a DNA molecule through a semi conservative method that splits the 2 strands of DNA and attaches a new strand to each one, creating a new DNA molecule?
    DNA Replication
