Document Summary
Assimilation or the dark energy or carbon fixation. Winter not much light don"t use co2 to make as much fixed sugars. 2. inorganic, doesn"t have hexose sugars via dark rxn are part of cane sugar or starch calvin take inorg c and fix it as organic c organic means theres c-h bonds inorganic means co2. 3 nadph and atp made from light rxn activated carriers and are used to turn oxidized co2 into e this makes hexose which are phosphorylated. Mg in stroma very impt purpose in enabling carbon fixation. 9 active site for catalytic activity is in the large subunit lys activate activity of rubisco. Getting co2 into carbon fixation (6c 5c) cycle is the rate. Co2 in rubisco isn"t the co2 that comes in and uses the c. 2c3keto 1-5bp unstable redistributed into 3 identical 3c sugars which would undergo reduction (in diagram) 12 sucrose = glu + fru amylose = glu.
