Document Summary

Photosynthesis- biological process converting light energy to chem energy, stored in g3p. Autotrophic- organism capable of synthesize organic compounds from inorganic sources, Heterotrophs- organism that cannot synthesize organic compounds from inorganic sources, and therefore must come from other organisms, Oxygen atoms released, are from the h20. Two distinct reactions in photosynthesis: ones requiring light(produces. 2 oxygen) and ones that don"t(convertings co2 into sugars). Calvin cycle- set of reactions using nadph/atp from light reactions to fixate. Carbon dioxide, reduction of fixed carbon(by nadph) to produce sugars, and the regeneration of substrate for fixation of co2(stroma). Nicotinamide adenine dinucleotide, used in photosynthesis as electron carrier, reduced during light reactions. Electrons from water are primary donor. membrane). Chloroplast- chlorophyll-containing organelle, w/ double membrane, where photosynthesis occurs(plants/algae). Also produces starch, amino acid, fatty acid, purine, and pyrimidine. Thylakoid- membrane bound network, of flattened sacs, within chloroplast(converts light energy to chemical energy)(stacks of these are called grana).
