Document Summary
Metabolic diversification microbial diversification: h2 based metabolism energy atp for the fixation of co2 cellular (organic) material nutrients that allowed the appearance of different metabolism. Protocell luca (h2 reduction of s h2s + atp + co2) Bacteria: acetogenic (h2 reduction of co2 atp + acetate) Chemoheterotrophic organic molecules taken from other organisms. Archaea: methanogenic (h2 reduction of co2 atp + methane) Light photosynthetic organisms are phototrophic organisms: 2n co2 + 2n h2o 2(ch2o) + 2n o2. Dark reaction: 3co2 + 6nadph + 5h2o + 9atp g3p + 6nadp + 2h + 9adp + 8pi, organisms: purple sulfer , purple nonsulfur, and green sulfur bacteria location: stroma. Oxygenic photosynthesis: eukaryotes and cyanobacteria, examples, plants, multicellular green, brown, red algae, unicellular protists, cyanobacteria, cyclic and non cyclic electron flow, co2 + h2o carbohydrate + o2. Anoxygenic photosynthesis: co2 + ha carbohydrate + a.
