What is carbon fixation?

Carbon fixation is the process where carbon dioxide (CO₂) is converted into organic compounds by autotrophic organisms like plants, algae, and some bacteria. It forms the basis of food production in ecosystems.

What are the four steps in the carbon fixation cycle?

The four steps are carbon fixation, where CO₂ joins RuBP; reduction, where compounds are converted to G3P; carbohydrate formation from some G3P; and RuBP regeneration to continue the cycle.

What is the C3, C4, and CAM pathway?

C3, C4, and CAM are plant carbon fixation methods. C3 fixes CO₂ into a 3-carbon compound via the Calvin cycle. C4 first forms a 4-carbon compound before the Calvin cycle. CAM plants fix CO₂ at night to save water.
