Lecture 11 Ch. 10 Photosynthesis: Sunlight Carbohydrates [produces oxygen] *Requires sunlight, carbon dioxide, and water * Cellular Photosynthesis Respiration Endergonic (takes Exergonic up energy) (releases energy) Reduces CO2 to Oxidizes sugar to sugar CO2 Light dependent reactions: H2O O2 Calvin Cycle (Dark reactions): CO2 sugar Absorption spectrum: graph to study pigments Action spectrum: rate of photosynthesis vs. Wavelength Visible spectrum- High energy ----------------- Low energy (Shorter wavelength) (Longer wavelength) Rubisco (slow and inefficient) - 8 active siteswhere CO2 is fixed; Photosynthesis, Photorespiration Calvin Cycle: 1. Fixation- CO2 reacts with Sunlight RuBP a. Produces 2, 3- phosphoglyerates 2. Reduction- The 2, 3- phosphoglerates: -Phosphorylated by ATP -Reduced by NADPH -Producing G3P H2O O2 Light cap. 3. Regeneration Reactions ATP+Pi ATP NADP+ H+ NADPH Calvin Cycle CO2 Sugars
