WebJan 12, 2024 · Phosphorus is one of the main elements needed for the growth and development of plant and crop quality. For soils with a phosphorus-fixation problem, phosphate-solubilizing bacteria (PSB) are capable of converting phosphorus from an unavailable form into an available form (HPO 42− or H 2 PO 4− ). WebDec 5, 2024 · This process is called carbon fixation, because CO 2 is “fixed” from its inorganic form into organic molecules. ATP and NADPH use their stored energy to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P. This type of reaction is called a reduction reaction, because it involves the gain of electrons.
