WebSugar is produced by all green plants and photosynthetic bacteria in a reaction sequence capable of forming carbon-carbon bonds. The very first steps occur independently of solar energy input, but to sustain the reaction, the products of initial fixation are phosphorylated and undergo a reduction in oxidation state. WebIn plants, carbon dioxide (CO 2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle.

The C fixed during photosynthesis is converted into sugar or sugar derivatives in photosynthetic source cells then is distributed to distal sink cells.

WebThe drawback to C4 photosynthesis is the extra energy in the form of ATP that is used to pump the 4-carbon acids to the bundle sheath cell and the pumping of the 3-carbon compound back to the mesophyll cell for conversion to PEP.
