5 Matching questions

  1. Steps of Noncyclic pathway (photophosphorlation)
  2. Fluoresce
  3. Photons
  4. Light-Dependent Reactions
  5. Types of Photosynthesis
  1. a packets of energy that travel in waves, one of these energizes one electron
  2. b when an electron returns to its ground state, releases light
  3. c 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)
  4. d 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)
  5. e C3 photosysthesis
    C4 photosynthesis
    CAM photosynthesis

5 Multiple choice questions

  1. C4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass
  2. cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts
  3. GOAL=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
  4. chlorophyll b (yellow green)
    carotenoids (orange)
  5. 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 True/False questions

  1. Stromainclosed by the inner membrane

          

  2. Energy of Light Rays (length)stacks of thylakoids

          

  3. Calvin Cyclepigment in chloroplasts that trap light

          

  4. summary of noncyclic pathwayIN= H2O, light, ADP, P, NADPH+
    OUT= ATP, NADPH, O2 (waste)
