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.


As a result, the photorespiration pathway is bypassed, and the wasteful loss of CO 2 common in C 3 carbon fixation pathway is minimized. Plants that first go through the C 4 pathway are better adapted than plants that solely go through the C 3 pathway under conditions of drought, high temperatures and low nitrogen or CO 2 concentrations.


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.

Difference Between C3, C4 and CAM pathway. July 10, 2017 By Rachna C 3 Comments. ... C3 plants provide a higher amount of protein than the C4 plants. Definition of C4 pathway or Hatch and Slack pathway. Plants, especially in the tropical region, follow this pathway.


Definition of C4, C4 PHOTOSYNTHETIC PATHWAY: Photosynthesis biological pathway whose carbon fixation products contain 4 carbons, as opposed to 3-carbon phophoclyceric acid.


Definition of C4 PATHWAY EVOLUTION: Changes in the C4 metabolic pathway where amino acids, aspartate C4 and alanine C3 replace malate and pyruvate in the shuttle process between cell types, a


C3, C4 and CAM are the three different processes that plants use to fix carbon during the process of photosynthesis. Fixing carbon is the way plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.

The C 3 carbon fixation pathway is in fact the initial phase of Calvin cycle.It starts with the enzyme rubisco catalyzing the carboxylation of Ribulose-1,5-bisphosphate by CO 2 producing a highly unstable 6-carbon intermediate known as 3-keto-2-carboxyarabinitol 1,5-bisphosphate, which splits instantaneously into two molecules of the more stable 3-phosphogylycerate, an organic compound ...
