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. WebThe phenomenon of phosphate fixation can be defined as conversion of soluble phosphorus to insoluble (i.e. solid phase) phosphorus or it may be defined as a process by which easily soluble and easily available phosphorus is converted to insoluble form and thus restricting its mobility and thereby decreasing its availability to crops.
