Document Summary

Photosynthesis- energy from light is captured & used to synthesize glucose & other org. molec. Glucose synthesis- 6co2 + 12 h2o + light energy --> c6h12o6 + 6o2 + 6h2o: redox rxn. Co2 - reduced during formation of glucose. H2o - oxidized during formation of o2: endergonic. Heterotroph- must consume organic molec from enviro to sustain life. Autotroph- sustain themselves by making org molec from inorganic sources. Life in biosphere driven by power of green plants. Cellular resp- c6h12o6 + 6o2 --> 6co2 + 6h2o + energy: uses glucose to form oxygen. Thylakoid membr- contains pigment molec incl chlorophyll. Stroma- fluid-filled region of chloroplast b/w inner & thylakoid membr. Light rxn- captures light energy: produces atp, nadph, o2. Calvin cycle- uses atp & nadph to use incorporate co2 into org molec: using glucose to make carbon dioxide. Travels as waves caused by oscillation of electric & magnetic fields. Diff types of em rad have diff wavelengths.
