Answer :
Final answer:
Carbon fixation is a part of photosynthesis where CO2 is added to RuBP to form 3-PGA and eventually glucose. The process is catalyzed by the enzyme RuBisCO and also involves the stages of reduction and regeneration.
Explanation:
Carbon fixation is a process in photosynthesis where carbon dioxide (CO2) combines with a five-carbon sugar, ribulose bisphosphate (RuBP), to form a six-carbon compound. This reaction is catalyzed by an enzyme called RuBisCO. The six-carbon compound is then broken down into two molecules of 3-phosphoglycerate (3-PGA). This cycle, known as the Calvin cycle, involves not only fixation, but also the stages of reduction and regeneration. Reduction uses ATP and NADPH to convert the 3-PGA into glyceraldehyde 3-phosphate (G3P), some of which is used to build glucose. The remaining G3P is used to regenerate RuBP, using additional ATP, which allows the cycle to continue with more carbon fixation.
