• Carbon fixation — is a process found in autotrophs (organisms that produce their own food), usually driven by photosynthesis, whereby carbon dioxide is changed into organic materials. Carbon fixation can also be carried out by the process of calcification in… …   Wikipedia

• C4 carbon fixation — is one of three biochemical mechanisms, along with C3 and CAM photosynthesis, used in carbon fixation. It is named for the 4 carbon molecule present in the first product of carbon fixation in these plants, in contrast to the 3 carbon molecule… …   Wikipedia

• C3 carbon fixation — is a metabolic pathway for carbon fixation in photosynthesis. This process converts carbon dioxide and ribulose bisphosphate (RuBP, a 5 carbon sugar) into 3 phosphoglycerate through the following reaction::6 CO2 + 6 RuBP → 12 3… …   Wikipedia
