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.


What Is the Definition of a C4 Pathway? The C4 pathway is a method plants use to convert atmospheric carbon dioxide into a chemical compound containing four carbons. About.com explains that plans that utilize this pathway usually originate in subtropical areas. Examples include maize, sugarcane, sorghum, millet and papyrus.

The C4 pathway 1. How are C4 plants differentfrom C3 plants?C4 plants are special :- They have a special type of leaf anatomy They tolerate higher temperatures They show a response to high light intensities They lack a process called photorespiration They have greater productivity of biomass.

carbon-fixations in C4 plants has a larger energy cost than in c3 plants, co2 fixation in c4 plants is more efficient than in c3 plants, the optimal temperature range for photosynthesis in c4 plants is higher than that for c3 plants, c4 plants have less rubisco than c3 plants


Difference Between C3, C4 and CAM pathway. July 10, 2017 By Rachna C 3 Comments. The assimilation of carbon dioxide from the sunlight, for the process of photosynthesis and then converting it to glucose (energy) synthesizing different product is the key difference between the three.


On 26 October 2000, Nature reported the discovery of both the C3 and C4 pathways in a marine diatom. In this unicellular organism, the two paths are kept separate by having the C4 path in the cytosol, and the C3 path confined to the chloroplast. The presence of a C4 pathway probably reflects the frequent low concentrations of CO 2 in ocean waters.
