Document Summary
Assimilation of co2: reason for all of this. Incorporate a non-organic carbon into organic biomass: main products, consume co2 and water, produce trioses phosphates, steps, calvin cycle, 15 enzymatic steps, most complex concepts **, easiest to understand if you divide it into 3 stages, 1. Carboxylation: actually add carbon, be the addition of co2 to a preexisting 5 carbon molecule (rubp) last molecule in calvin cycle to which you add a co2. Ppt19 (12-14) ppt20 (1-9: phosphate on each end, ***fructose 1,6 bisphosphate. Reduction: reducing molecule to triose phosphates (like 3 carbon units analogous to glucose, that is what you want to make, way, use reducing power in nadph, pretty good reducing agent, similar to nadh, 1. Phosphorylate it to generate a double molecule: 3. Reduce it with nadph to glyceraldehyde 3-phosphate (gap) interconverted with dhap: 4. Molecules can be joined via aldolase to form fructose 1,6- bisphosphate: 5.
