This catalyzed reaction produces a 6-carbon intermediate which decays almost immediately to form two molecules of the 3-carbon compound 3-phosphoglyceric acid (3PGA). The cycle is light-independent because it takes place after the energy has been captured from sunlight.. Photosynthetic organisms use sunlight to create energy which is stored in the form of several chemical compounds. in the stroma of a chloroplast cell. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.
