Chapter 10: Photosynthesis: Energy from Sunlight OVERVIEW Chapter 10 deals with photosynthesis, the process that underlies almost all energy relationships among life on Earth. The chapter primarily focuses on the two sets of reactions of photosynthesis: the light reactions and the Calvin cycle. The role of sunlight and light absorbing pigments in the harvesting of light energy is presented followed by carbon fixation and its variations in C 3 , C 4 , and CAM plants. Photosynthesis is then placed within the context of the plant’s overall metabolic processes and the larger ecology of life on Earth. KEY CONCEPTS 1. Photosynthesizing plants take in CO 2 , water, and light energy, producing O 2 and carbohydrate. The overall reaction is 6 CO 2 + 12 H 2 O + light → C 6 H 12 O 6 + 6 O 2 + 6 H 2 O 2. In the light reactions of photosynthesis, electron flow and photophosphorylation produce ATP and reduce NADP + to NADPH + H + . 3. ATP and NADPH + H + are needed for the reactions that fix and reduce CO 2 in the Calvin cycle, forming sugars.
