Photosynthesis: Review and Expansion We have been concealing extensive truth from you! Not 1 stage… more like 50! light CO 2 + H 2 O 2 + CH 2 O chlorophyll Light Reactions: maybe 25 stages light ADP + P + NADP + H 2 O 2 + NADPH 2 + ATP chlorophyll Interdependent! Calvin Cycle Reactions: maybe 25 stages AKA: Dark Reactions ATP + NADPH 2 + CO 2 CH 2 O + NADP + ADP + P light In total: CO 2 + H 2 O 2 + CH 2 O chlorophyll The light and Calvin cycle responses are associated… no dull responses!

Slide 11

100% Photosynthetic Rate 0 What wavelengths of light drive photosynthesis? Activity Spectrum green light mirrored despite everything some drives photosynthesis obvious range 400 500 600 700 nm wavelength (nm) Light past 700 nm has deficient vitality to drive photosynthesis
