Photosynthesis
Photosynthesis is the process used to trap light energy and convert it to chemical bond energy, forming organic compounds. Photosynthesis is divided into two groups: the light reactions and the dark reactions. The light reactions produce ATP, NADPH and oxygen. The dark reactions use this energy to convert carbon dioxide to glucose. The overall process of photosynthesis is: . The reactions both take place in the chloroplasts of plants. Light reactions occur in the thylakoids and the dark reactions occur in the stroma. In this experiment I used DCPIP, which is blue in color, as an artificial electron acceptor in place of NADP+.
