The three main events in the photosynthetic pathway are Light capturing events, light dependent reactions and light independent reactions. During the light capturing events, Chlorophyll (main pigment), and other pigments absorb wavelengths of light. There are many different combinations of the wavelengths of light, and they can be seen as different colors. The pigments are molecules that absorb and reflect the light. The wavelengths that are absorbed by the pigment are used to work; the other is just what we see. At this time the wavelengths “excite” electrons, which will then enter into chemical reactions that produce ATP. This corresponds with light dependent reactions or light reactions. In a light reaction, the “excited” electrons

The ATP and NADPH that are produced through the light dependent reaction, move to the Stroma for the next event, the light independent reaction, or dark reaction, or Calvin cycle. In the dark reaction, Carbon Dioxide and recycled 5 carbon sugar called ribulose are energized and reduced by the ATP and the NADPH made in the light reaction to form Glyceraldehyde-3-phosphate, the product of photosynthesis. This can be used for many things by organisms and is a very important substance. Eldon D. Enger, Frederick Ross, David B. Bailey. Concepts in Biology . 13th. Ny: McGraw-Hill, 2009....
