5 Matching questions

  1. Steps of Chemiosmosis
  2. Mesophyll
  3. Photosystems
  4. Types of Photosynthesis
  5. Granum (grana plural)
  1. a 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
  2. b cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts
  3. c stacks of thylakoids
  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 C3 photosysthesis
    C4 photosynthesis
    CAM photosynthesis

5 Multiple choice questions

  1. 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)
  2. cyclic photophosphorlation produces ATP only
    simplest form
    electrons recycle so none are needed
    not O2 released, bc H2O is not split
  3. 3rd membrane inside the stroma
    set of membranes with an internal space (lumen)
    arranged into stacks
    where chlorophyll and other pigments are stored
  4. long=less energetic
    short=more energetic
  5. pigment in chloroplasts that trap light

5 True/False questions

  1. Chemiosmosispackets of energy that travel in waves, one of these energizes one electron

          

  2. summary of noncyclic pathwaycyclic photophosphorlation produces ATP only
    simplest form
    electrons recycle so none are needed
    not O2 released, bc H2O is not split

          

  3. Fluoresceinclosed by the inner membrane

          

  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. Overall Reaction6CO2 +12H20 = C6H12O6 + 6O2

    CO2 and the C6H12O6 are involved in the reduction reaction, H20 and O2 are involved in the oxidation reaction
