Ribulose-1, 5- diphosphate is the receptor of CO2 in photosynthesis. Under the action of ribulose-1, 5- diphosphate carboxylase/oxygenase (Rubisco), it forms an intermediate product with CO2, which reacts with 1 H2O to form 2 molecules of glyceric acid -3- phosphate (.
Chloroplast membrane:
The absorption peak process of chlorophyll a and chlorophyll b: two sets of photosynthetic systems on chloroplast membrane: photosynthetic system I and photosynthetic system II. (Photosynthetic system I is more primitive than photosynthetic system II, but electron transfer begins first. ) Under illumination, photons with wavelength of 680nm and 700nm are absorbed respectively, and the electrons obtained during the photolysis of water molecules are continuously transferred as energy. (Only a few chlorophyll in a special state can transfer electrons.
