Bio1152 Chapter 10 Photosynthesis
  1. Plants and other                  are the            of ecosystems.

  2. Photoautotrophs can convert solar energy into the           energy in food by a process called                 .

  3. Photosynthesis is a        process where water is           and carbon dioxide is          to          .

  4. In plants, photosynthesis occurs in organelles called chloroplasts, which contain its own              pigment molecules.

  5. There are two major stages: the        reactions and the         cycle (light-independent reactions).

    • The light reactions occur in the        , where pigment molecules located in a photosystem absorb light and their electrons reach an          state.

    • Each excited electron is passed through an           transport chain (ETC) and another photosystem, where the energy is used to produce      and reduce NADP+ to        .

    • The Calvin cycle occurs in the         to synthesize        from carbon dioxide.

  6.     plants are adapted to hot, dry climates by incorporating CO2 into       -carbon as the substrate in the Calvin cycle.

  7. The production of          carbon compounds from            CO2 is called         fixation.
