Chapter 10: Photosynthesis I. Two Distinct Sets of Reactions in photosynthesis. Each take place at different locations in the chloroplast II. Chlorophyll captures light energy using the Antenna Complex and The Reaction Center III. The Discovery of Photosystems I and II & the Z Scheme Photosystem II : Electrons from ETC make ATP (via ATP Synthase) Photosystem I : Electrons are used to generate NADPH IV. How is Carbon reduced to produce glucose? The Calvin Cycle : 3 Phases : Fixation, Reduction, Regeneration using Rubisco Key Concepts: Light Energy is converted to chemical energy. Electrons are utilized in electron transport chains to make ATP and NADPH needed to convert CO 2 to CH 2 O.

Unformatted text preview: vs Quote of the Day from Scott Freeman: • “Chemists have synthesized an amazing diversity of compounds from relatively simple starting materials, but their achievements PALE in comparison to cells that can synthesize sugar from just carbon dioxide, water, and sunlight.” The Structure of Chloroplast Chlorophyll is located in the Thylakoid Inner Membrane How Does Chlorophyll Capture Light Energy? Chlorophyll is exciting LIGHT is both waves and particles (photons) Photosynthetic Pigments Absorb Photons of Light Fig 10.4 Fig 10.4 Why do plants appear green? High Energy Low Energy Photons from which color(s) are most effective at triggering photosynthesis? 1 2 3 4 0% 0% 0% 0% 1. Orange 2. Green 3. Blue 4. Blue and Red Given what we know about chlorophyll, which wavelengths of light are most effective at stimulating photosynthesis? What Is the Role of Carotenoids and Other Accessory Pigments?...
