Photosynthesis 1% sunlight is converted to chemical energy by plants Fixation of carbon dioxide and evolution of oxygen Overall reaction: 6CO 2 + 6H 2 O 1 glucose + 6 O 2 granum Light reactions -Light-induced electron transfer -Thylakoid membrane -H 2 O + 3ADP + 2NADP + → O 2 + 3ATP + NADPH Dark reactions -CO 2 fixation in the stroma -Biosynthetic reactions -Requires ATP and NADPH Two components in photosynthesis: Chloroplast 1
