CO 2 + H 2 O C 6 H 12 O 6 + O 2 Algae, plants, protists Photosynthesis - converting CO 2 into glucose Store energy Release oxygen Uses CO 2 Photosynthesis Release energy Use oxygen Releases CO 2 Respiration Interconnections Structures of Photosynthesis - Figure 7-2 Overview of Photosynthesis - page 118 Chlorophyll: main pigment; absorbs violet, blue, and red light; reflects green Carotenoids: accessory pigment; absorbs blue and green light; reflects yellow, orange, and red Pigments Light - Dependent Reactions Color is reflected wavelengths; different wavelengths are different colors Why are leaves green? Photosystems: imbedded in thylakoid membranes; II used before I (page 119) Pigments absorb light energy, lose electrons: enter electron transfer chains Make ATP and NADPH Split water and release O 2 Pigment electrons are replaced Occur in thylakoids Light Dependent Reactions - Figure 7-4
