      of photosynthesis lies in the rapid separation of electrically charged products after an initial light reaction and the subsequent efficient formation of stable products that can be used to drive anabolic reactions (molecule-building reactions) in the cell. The section on plastids in Chapter 3 should be con-sulted before reading this chapter.

      In the dark, neither O 2 production nor dye reduction took place. This was the first specific clue to how absorbed light energy is converted into chemical energy: it causes electrons to flow from H 2O to an electron acceptor. Moreover, Hill found that CO 2 was not required for this reaction, nor was it reduced to a stable form under these ...

      zThe entire process of photosynthesis takes place inside the chloroplast. The structure of chloroplast is such that the light dependent (light reaction) and light independent (Dark reaction) reactions take place at different sites in the same organelle. zThe thylakoids have the pigments and other necessary components to absorb

      from carbon dioxide and water. The overall reaction of photosynthesis can be given in a simple form as follows: In green plants, water is the hydrogen donor and it undergoes oxidation to produce oxygen. Photosynthesis occurs in two stages, viz. light reaction and dark reaction. The light reaction …

      products of the Light Reaction are used to form C-C covalent bonds of carbohydrates. The Dark Reactions can usually occur in the dark, if the energy carriers from the light process are present. Recent evidence suggests that a major enzyme of the Dark Reaction is indirectly stimulated by light, thus the term Dark Reaction is somewhat of a misnomer.

      Dark Reactions March 20, 2002 Bryant Miles The light reactions of photosynthesis transform the energy of light into high energy ATP and NADPH. The dark reactions reduced carbon dioxide to form carbohydrates. These reactions are called dark reactions because these reactions do not directly depend on photons of light. NADPH is the anabolic
