5 Matching Questions

  1. Energy of Light Rays (length)
  2. C3 Photosynthesis
  3. thylakoid
  4. Other pigments
  5. Photons
  1. a long=less energetic
    short=more energetic
  2. b packets of energy that travel in waves, one of these energizes one electron
  3. c most plants
    goes through the C3 pathway
    normal photosynthesis
  4. d 3rd membrane inside the stroma
    set of membranes with an internal space (lumen)
    arranged into stacks
    where chlorophyll and other pigments are stored
  5. e chlorophyll b (yellow green)
    carotenoids (orange)

5 Multiple Choice Questions

  1. process that produceds ATP (ATP synthesis)
  2. 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)
  3. GOAL=convert light energy to chemical energy
    1. occurs in thylakoid membranes
    2. light energy causes chlorophyll to spit out high energy electrons
    3. Electrons are replaced from H20
    4. Produce ATP and NADPH (electron carrier)
  4. 6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction
  5. bright green chlorophyll A
    absorbs reds and blues, reflects green and yellow

5 True/False Questions

  1. Stomataholes on the underside of a leaf where gas is released


  2. Types of PhotosynthesisC4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass


  3. Cyclic pathwayscyclic photophosphorlation produces ATP only
    simplest form
    electrons recycle so none are needed
    not O2 released, bc H2O is not split


  4. CAM photosynthesisonly 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. Calvin Cyclepigment in chloroplasts that trap light
