photosynthesis? A. Not all wavelengths are equally effective for photosynthesis. B. There must be accessory pigments that broaden the spectrum of light that contributes energy for photosynthesis. C. The red and blue areas of the spectrum are most effective in driving photosynthesis. D. Chlorophyll owes its color to the absorption of green light.

Chapter 23 – The Calvin Cycle (CO 2 Fixation) The “Dark” Reactions • Reductive conversion of CO 2 into carbohydrates • Process is powered by ATP and NADPH (formed during the light reactions of photosynthesis) TheCO 2 fixation pathway has several names: •The reductive pentose phosphate (RPP) pathway. •The C 3 pathway.

photosynthesis: the light reactions, which capture solar energy and transform it into chemical energy; and the Calvin cycle, which uses that chemical energy to make the organic mol-ecules of food. Finally, we’ll consider some aspects of photo-synthesis from an evolutionary perspective. CONCEPT 8.1 Photosynthesis converts light

Photosynthesis in a Nutshell: • Light Dependent Reaction – H 2O and light go in – ATP and NADPH come out and go to the Calvin Cycle (L.I.R) – Oxygen come out as waste • Light Independent Reaction – CO 2 goes in – ATP and NADPH used for energy – Glucose (C 6H 12O 6) comes out 22

Light reactions elevate electrons in 2 steps (PS II & PS I) PS II generates energy as ATP PS I generates reducing power as NADPH Cyclic Photophosphorylation If PS I can’t pass electron to NADP, it cycles back to PS II & makes more ATP, but no NADPH coordinates light reactions to Calvin cycle Calvin cycle uses more ATP than NADPH

Thefirst hypothesis abouttherole of light in photosynthesis came very appropriately from Jan Ingenhousz, who some years earlier had madethe epochal discovery that it is "the influence of the light of the sun upon the plant" (1) that is responsible for the "restorative" effect of vegetation on "bad" air-an observation first made in 1771 by Joseph
