FAQ
Frequently Asked Questions
No. Carbon fixation is a specific stage within the broader process of photosynthesis. Photosynthesis includes capturing light energy and using it to drive carbon fixation.
Yes. Certain bacteria and archaea, such as cyanobacteria and some deep-sea microorganisms, are also capable of biological carbon fixation.
It is a natural process that removes CO2, a major greenhouse gas, from the atmosphere and incorporates it into living biomass and soil, acting as a carbon sink.
The main enzyme is Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly abbreviated as RuBisCO.
The biochemical process by which atmospheric carbon dioxide is converted into organic compounds by living organisms, primarily through photosynthesis.
Carbon fixation is usually technical/scientific in register.
