5 Written questions

5 Matching questions

  1. Photosystems
  2. C3 Photosynthesis
  3. Steps of Chemiosmosis
  4. Mesophyll
  5. summary of noncyclic pathway
  1. a most plants
    goes through the C3 pathway
    normal photosynthesis
  2. b 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
  3. c cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts
  4. d 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)
  5. e IN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)

5 Multiple choice questions

  1. when an electron returns to its ground state, releases light
  2. packets of energy that travel in waves, one of these energizes one electron
  3. 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)
    In-ATP, NADPH, CO2
    Out- Glucose, ADP, NADPH+
  4. long=less energetic
    short=more energetic
  5. plants use this as a back up
    bacteria use it to make ATP from sunlight
    probably the first system

5 True/False questions

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


  2. 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


  3. Chlorophyllpigment in chloroplasts that trap light


  4. Main plant pigmentchlorophyll b (yellow green)
    carotenoids (orange)


  5. Cyclic pathwayspigment in chloroplasts that trap light
