5 Matching Questions

  1. Overall Reaction
  2. Photosystems
  3. Chlorophyll
  4. Mesophyll
  5. Granum (grana plural)
  1. a pigment in chloroplasts that trap light
  2. b stacks of thylakoids
  3. c where chlorophyll is stored
    include antenna complex/reaction center
    2 types= photosystem II and photosystem I (in order in which they occur, named in order of discovery)
  4. d 6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction
  5. e cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts

5 Multiple Choice Questions

  1. long=less energetic
    short=more energetic
  2. C3 photosysthesis
    C4 photosynthesis
    CAM photosynthesis
  3. chlorophyll b (yellow green)
    carotenoids (orange)
  4. IN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)
  5. 3rd membrane inside the stroma
    set of membranes with an internal space (lumen)
    arranged into stacks
    where chlorophyll and other pigments are stored

5 True/False Questions

  1. Steps of Chemiosmosis1. 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

          

  2. C4 photosynthesisC4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass

          

  3. Chemiosmosispackets of energy that travel in waves, one of these energizes one electron

          

  4. Why do cyclic pathways exist?plants use this as a back up
    bacteria use it to make ATP from sunlight
    probably the first system

          

  5. CAM photosynthesisC4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass
