Show Answers:

  1. distinguish between photoautotrophs and chemoautotrophs
    • photoautotrophs: energy from sun
    • chemoautotrophs: energy from inorganic chemicals
  2. why is chlorophyll green?
    reflects green light but absorbs other colors
  3. why do leaves turn orange and yellow in the autumn?
    green stops reflecting because it's too cold for the chlorophyll A & B to work so they die
  4. explain the role of electron carriers in photosynthesis and give an example.
    • store energy, transport to the electron transport chain.
    • exp: ATP & NADPH
  5. summarize how chemical energy is formed from light during photosynthesis
    photosynthesis process absorbs light and uses water and carbon dioxide to form glucose energy. Does this through light dependent reactions and calvin cycle
  6. what is the role of hydrogen ions in the conversion of ADP to ADP
    they diffuse through the ATP synthase creating energy that allowed pi to bond to ATP
  7. what does the calvin cycle do
    • produces sugar & NADP
    • produces it form CO2, ATP, NADPH
  8. describe the relationship between the light dependent reactions and the calvin cycle
    light dependent: produces what is necessary for the calvin cycle to occur
  9. what is the equation for photosynthesis
    6CO2+6H2O+(light) --> 6O2+C6H1206
  10. what is the equation for cellular respiration
    6O2+C6H1206 --> 6C02+6H2O+(energy)
  11. list the three main stages of cellular respiration in order. Where does each stage take place in the cell?
    • Glycolysis: cytoplasm
    • Krebs Cycle: mitochondria
    • (ETC): inner membrane of the mitochondria
  12. describe the glycolysis in terms of energy input, output, and net gain of ATP
    • input: 2
    • output: 4
    • net gain: 2
  13. why is the krebs cycle also known as the citric acid cycle?
    one of the molecules it forms is made of citric acid
  14. what role does oxygen play in the electron transport chain?
    it combines w/ hydrogen ions which combines w/ electrons to from water
  15. what is the total net gain in ATP molecules per glucose molecule?
    • 36
    • 2: glycolysis
    • 2: krebs cycle
    • 32: ETC
  16. give two examples of fermentation
    saki, cramp in leg
  17. what are the two types of fermentation? how do their products differ?
    • alcoholic & lactic acid fermentation
    • lactic acid: eukaryotes
    • alcoholic: prokaryotes
  18. lactic acid fermentation produces
    lactic acid
  19. alcoholic fermentation produces
    ethol alcohol
  20. what three sources of ATP does your body use during a long aerobic exercise session?
    • glycolysis
    • krebs cycle
    • fermentation (aerobic fermentation)
  21. contrast photosynthesis with cellular respiration
    complamentary. what one produces the other uses
  22. how are photosynthesis and cellular respiration interdependent?
    photosynthesis is produced by cellular respiration
