5 Matching Questions

  1. Chlorophyll
  2. Stroma
  3. Overall Reaction
  4. Fluoresce
  5. Photons
  1. a packets of energy that travel in waves, one of these energizes one electron
  2. b pigment in chloroplasts that trap light
  3. c inclosed by the inner membrane
  4. d when an electron returns to its ground state, releases light
  5. e 6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction

5 Multiple Choice Questions

  1. plants use this as a back up
    bacteria use it to make ATP from sunlight
    probably the first system
  2. cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts
  3. chlorophyll b (yellow green)
    carotenoids (orange)
  4. 1. Electrons pass from one membrane protein to the next, giving up energy as they pass
    2. fuels hydrogen ion pump, which pump H+ ions (AKA protons) into thylakoid space
    3. H+ ion moves back through ATP synthase, fueling this enzyme that synthesizes ATP
  5. IN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)

5 True/False Questions

  1. Calvin Cyclewhat most plants use for carbon fixation
    series of redox reactions
    each cycle produces 1/2 glucose molecule
    1. take in CO2
    2. Reduce CO2, which produced organic molecules
    3. recycle/regenerate RuBP (molecule which CO2 is fixed to)
    SUMMARY=
    In-ATP, NADPH, CO2
    Out- Glucose, ADP, NADPH+

          

  2. Light-Dependent Reactions6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction

          

  3. Types of Photosynthesismost plants
    goes through the C3 pathway
    normal photosynthesis

          

  4. Steps of Noncyclic pathway (photophosphorlation)1. Light energizes 2 electrons (source=H2O, energy from this splitting goes to photosystem II)
    2. High energy electrons passed to electron transport chain
    3. release energy as they pass through the chain (fuels chemiosmosis that produces ATP)
    4. low energy electrons from transport chain pass to photosystem I
    5. energized again from the sun
    6 high energy electrons move to 2nd electron transport chain, then to electron carrier (NADPH)

          

  5. Photosystemspackets of energy that travel in waves, one of these energizes one electron
