C 4 carbon fixation or the Hatch–Slack pathway is a photosynthetic process in some plants. It is the first step in extracting carbon from carbon dioxide to be able to use it in sugar and other biomolecules. It is one of three known processes for carbon fixation."C 4" refers to the four-carbon molecule that is the first product of this type of carbon fixation.


Science · Biology · Photosynthesis · Photorespiration: C3, C4, and CAM plants C3, C4, and CAM plants How the C4 and CAM pathways help minimize photorespiration.


Corn,sugarcane and some shrubs are example of plants that follows C4 pathway. Calvin pathway is a common pathway in both C3 plants and C4 plants but it takes place only in the mesophyll cells of the C3 Plants but not in the C4 Plants. To know more about C3 and C4 pathway and photosynthesis in plants, vist BYJU’S.


Based on this idea Hatch & Slack worked out an alternate pathway of carbon fixation in sugarcane & it is called as Hatch & Slack cycle or Beta Carboxylation pathway or C4 Cycle or Dicarboxylic ...


The C4 photosynthetic carbon cycle is an elaborated addition to the C3 photosynthetic pathway. It evolved as an adaptation to high light intensities, high temperatures, and dryness. Therefore, C4 plants dominate grassland floras and biomass production in the warmer climates of the tropical and


C4 Photosynthesis. C4 is an efficient biochemical modification of the C3 Plants. In this pathway, carbon is captured into the mesophyll cells and transported to the Bundle-sheath cells where Calvin cycle occurs. CO2 molecules combine with Phosphoenolpyruvate (PEP) and form 4-carbon compound oxaloacetate, thus the process called C4 Pathway ...


What Is the Definition of a C4 Pathway? ... Reference.com says that C4 photosynthesis gives plants an advantage over those using the classic C3 type of photosynthesis in drought conditions as well as in locations where carbon dioxide and nitrogen are limited. In C3 plants, as much as 97 percent of the water is lost due to transpiration.


Photorespiration and C4 Plants All plants carry on photosynthesis by adding carbon dioxide (CO 2) to a phosphorylated 5-carbon sugar called ribulose bisphosphate. This reaction is catalyzed by the enzyme ribulose bisphosphate carboxylase oxygenase (RUBISCO). The resulting 6-carbon compound breaks down into two molecules of 3-phosphoglyceric ...


Photosynthesis - Carbon fixation in C4 plants: Certain plants—including the important crops sugarcane and corn (maize), as well as other diverse species that are thought to have expanded their geographic ranges into tropical areas—have developed a special mechanism of carbon fixation that largely prevents photorespiration. The leaves of these plants have special anatomy and biochemistry.
