5 Written questions

5 Matching questions

  1. Fluoresce
  2. Cyclic pathways
  3. Stroma
  4. Calvin Cycle
  5. Granum (grana plural)
  1. a when an electron returns to its ground state, releases light
  2. b stacks of thylakoids
  3. c inclosed by the inner membrane
  4. d what 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+
  5. e cyclic photophosphorlation produces ATP only
    simplest form
    electrons recycle so none are needed
    not O2 released, bc H2O is not split

5 Multiple choice questions

  1. 6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction
  2. 3rd membrane inside the stroma
    set of membranes with an internal space (lumen)
    arranged into stacks
    where chlorophyll and other pigments are stored
  3. process that produceds ATP (ATP synthesis)
  4. C4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass
  5. only fix carbon at night
    dry, desert environment
    only opens the stomata at night, which converts to a temporary carbon storage molecule, which is then used in the calvin cycle
    ex. cactus, aloe plants, succulants

5 True/False questions

  1. Mesophyllcells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts

          

  2. Chlorophyllpigment in chloroplasts that trap light

          

  3. summary of noncyclic pathwayIN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)

          

  4. 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

          

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