Carbon Fixation

From Proteopedia

Jump to: navigation, search

Biological carbon fixation or сarbon assimilation is the process by which inorganic carbon (particularly in the form of carbon dioxide) is converted to organic compounds by living organisms. See also [1].

Organisms that grow by fixing carbon are called autotrophs, which include photoautotrophs (which use sunlight), and lithoautotrophs (which use inorganic oxidation).

Several autotrophic carbon fixation pathways are known:

1) Calvin cycle

2) Reverse Krebs cycle
