This malate enters the bundle-sheath cell and is decarboxylated inside the chloroplasts. However, its carboxylating enzyme Rubisco also accepts oxygen, thus producing 2-phosphoglycolate. This is the C4 pathway net reaction: The Krebs cycle is also known as the Calvin cycle Pyruvic acid cycle Carbon - oxygen cycle Citric acid cycle . This set of reactions is also called carbon fixation. By having a high concentration of carbon dioxide at the site of the Calvin cycle, plants are able to prevent very high rates of wasteful photorespiration when growing in hot climates. The resulting product of rubisco, 3-phosphoglycerate, is converted into fructose 6-phosphate which isomerizes to glucose 1-phosphate and glucose 6-phosphate. The transportation of the carbon dioxide in the C4 pathway begins inside the mesophyll cell when the carbon dioxide and phosphoenolpyruvate is condensed to form oxaloacetate. Phosphoglycolate salvage pathways were extensively studied in photoautotrophs but remain uncharacterized in chemolithoautotrophs using the Calvin cycle. This step is also sometimes referred to as the 'Calvin-Benson Cycle,' as it gets its name from the scientists who discovered it. These changes help couple the Calvin cycle to the light reactions. This decarboxylation of C4 compounds in the bundle-sheath cells have the ability to maintain high concentrations of carbon dioxide in the Calvin cycle.
