5 Matching questions

  1. CAM photosynthesis
  2. thylakoid
  3. Chemiosmosis
  4. Steps of Noncyclic pathway (photophosphorlation)
  5. C3 Photosynthesis
  1. a process that produceds ATP (ATP synthesis)
  2. b 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. 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 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 Multiple choice questions

  1. packets of energy that travel in waves, one of these energizes one electron
  2. bright green chlorophyll A
    absorbs reds and blues, reflects green and yellow
  3. pigment in chloroplasts that trap light
  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. stacks of thylakoids

5 True/False questions

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

          

  2. Light Independent Reactions/Carbon Fixation ReactionsGOAL=convert to storable form of chemical energy
    1. independent of light
    2. conver inorganic forms of carbon (CO2) into organic form to create glucose
    3. Uses products of the Light-Dependent reactions to fix the carbon

          

  3. Calvin Cyclepigment in chloroplasts that trap light

          

  4. Energy of Light Rays (length)long=less energetic
    short=more energetic

          

  5. Fluoresceholes on the underside of a leaf where gas is released
