Chapter 7 Photosynthesis: Acquiring Energy from the Sun Review
  1. Photosynthesis transforms light energy into the chemical energy of via pigments.
     
     
     
     
  2. In plants, photosynthesis takes place in the leaves in two steps: the light- reactions and the light- reactions (Calvin cycle).
     
     
     
     
  3. Groups of pigments are embedded in membranes and organized into with embedded proteins.
     
     
     
     
  4. Light energy captured in the photosystems is used to excite that are passed to two transport systems.
     
     
     
     
  5. The two transport systems harvest the energy in the electrons to produce and .
     
     
     
     
    Review: light-dependent reactions.
     
     
     
     
  6. The Calvin cycle occurs in the of chloroplasts, and use products of the light-dependent reactions, ATP and , to build carbohydrates from CO2.
