Lecture 6 photosynthesis 01/22/16 anuj gupta definition of photosynthesis, oxidation, reduction, oxidation-reduction reaction, light reactions, calvin cycle, redox potential, chloroplast, thylakoid membrane, lumen, p680, Photosynthesis: aka carbon fixation or primary productivity, take atmospheric co2 or co2(aq) from such an environment and use the energy of light to drive the formation of co2 into sugar, endergonic process. The g in 1 glucose molecule is higher than 6 molecules of. Co2: also an anabolic process, and an oxidation-reduction reaction, there is no usable energy in co2. This is because there are no readily accessible or usable electrons. It"s a fully oxidized form of c. but there"s lots of usable energy (because of lots accessible electrons). We know this because there are lots of c-h bonds. Molecules that have lots of g have lots of c-h bonds (e. g fat, gasoline): e. g. photosynthesis. Note that the oxidation of water and reduction of co2 do not occur near each other.
