              energy-giving nutrients like sugar and starch (See Figure 10.3d).
                  This explanation of what actually goes on has been simplified a
              thousandfold, but is still too complex to understand. In reality, the
              explanation of reactions that take place during photosynthesis is too
              long to fit on these pages. No laboratory on Earth is capable of dupli-
              cating this energy transformation, carried out in organelles that are
              thousandths of a millimeter in size. A system placed within the mem-





                   pendent reactions, takes place in the stroma (See Figure 10.3b). Then, via a
                   complex series of processes still not completely understood, carbon diox-
                   ide, NADPH, and ATP are converted into the carbohydrates that facilitate
                   the continuation of life. Within a tiny chloroplast about a thousandth of a
                   millimeter in size, and an even tinier membrane within that chloroplast a
                   hundred millionth of a meter in size, are produced food and oxygen for all
                   human and animal life.
