1/5/12 12:13 PM Photosynthesis- a building rxn, uphill rxn Starts w/ CO2 and add Hydrogen until we get a high energy sugar [G3P] A process that converts solar energy to chemical energy -needs more energy to keep going *Autotrophs- living things that made their own food without using organic molecules from other living things espes: photoautotrophs- use photosynthesis for food making plants, algae, & other protests must have a way to capture the protons of the light pigments -> Light Pigments Different pigments capture different wavelengths (WL) of light P.190 wavelength/ rainbow chart Gamma ray Frequency is the height from the crest (top) to the troth (bottom) Longer WL= lower energy
