Chapter 8, page 8 Chapter 8 Highlights: I. The Interactions of Light and Pigments A. Absorbed wavelengths correlate with biological activity B. Photosynthesis uses energy absorbed by several pigments C. Light absorption results in photochemical change D. Excited chlorophyll in the reaction center acts as a reducing agent for electron transport II. The Light Reactions: Electron Transport, Reductions, and Photophosphorylation A. Both cyclic and noncyclic photosystemsdrive electron transport that drives protons into the thylakoid interior. B. Noncyclic electron transport extracts electrons and protons from H 2 0 to make O 2 , then these electrons are used to convert NADP + to NADPH+H + . C. Chemiosmosis is the source of the ATP produced in photophosphorylation. III. The Dark Reactions C. Making Carbohydrate from CO 2 : The Calvin–Benson Cycle D. The Calvin–Benson cycle is made up of three processes IV. Photorespiration and Its Consequences A. Rubisco catalyzes RuBP reaction with O 2 as well as CO 2 B. C3 vs. C4 plants: C4 plants can mimimize photorespiration when CO 2 concentrations are high.
