5 Written questions

5 Matching questions

  1. Chemiosmosis
  2. summary of noncyclic pathway
  3. Stomata
  4. Overall Reaction
  5. Why do cyclic pathways exist?
  1. a IN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)
  2. b 6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction
  3. c process that produceds ATP (ATP synthesis)
  4. d plants use this as a back up
    bacteria use it to make ATP from sunlight
    probably the first system
  5. e holes on the underside of a leaf where gas is released

5 Multiple choice questions

  1. most plants
    goes through the C3 pathway
    normal photosynthesis
  2. 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)
  3. bright green chlorophyll A
    absorbs reds and blues, reflects green and yellow
  4. cyclic photophosphorlation produces ATP only
    simplest form
    electrons recycle so none are needed
    not O2 released, bc H2O is not split
  5. long=less energetic
    short=more energetic

5 True/False questions

  1. Other pigmentschlorophyll b (yellow green)
    carotenoids (orange)


  2. Light Independent Reactions/Carbon Fixation ReactionsGOAL=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)


  3. Photosystemswhere 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. 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)
    In-ATP, NADPH, CO2
    Out- Glucose, ADP, NADPH+


  5. Mesophyllpigment in chloroplasts that trap light
