Document Summary
Their source of energy is light and their source of carbon is. These phototrophic organisms include: plants, algae, microscopic algae, and cyanobacteria. Phototrophic bacteria came later from chemoautotrophs: don"t find photoautotrophic metabolisms in archaea other than. Use enenergy of light to produce atp, Know this but won"t use it to create organic compounds. Only photoheterotrophs are phototrophic bacteria and some archaea. Photosynthetic organisms are phototrophic organisms use the chemical energy obtained form light to synthetize organic ocmpounds. Pmf that will then produce atp from adp and nadph form the reduction of nadp: this energy and reducing power will then fix the co2 from the atmosphere into g3p and feed it into the general pathways. Nadph will then go into the stroma to fix the co2: the dark reactions take place in the stroma. Chloroplasts are found in microscopic algae, algae, and plants. 680nm: pi absorbs 700nm, so: light hits the antenna pigments energy will transfer from molecule.
