Answer :
Carbon fixation correctly describes the conversion of CO2 into an organic compound, which is a process catalyzed by the enzyme RuBisCO during the Calvin cycle of photosynthesis resulting in the formation of 3-PGA. The correct option is a.
The correct answer to the question of which statement accurately describes carbon fixation is:
a. the conversion of CO2 into an organic compound
Carbon fixation is a process that occurs during the Calvin cycle of photosynthesis, where RuBisCO catalyzes a reaction between CO2 and RuBP, forming 3-phospho glyceric acid (3-PGA), which is then used to create organic compounds such as glucose. Later in the Calvin cycle, ATP and NADPH are used in the reduction stage to convert 3-PGA into another molecule called glyceraldehyde 3-phosphate (G3P), which can be used to form carbohydrates. However, the initial step where CO2 is converted into an organic compound (3-PGA) defines carbon fixation.
Answer:
answer A the conversion of CO2 to an organic compound.
Explanation:
Carbon fixation is first step of Calvin cycle. The carbon fixation is process during which inorganic CO2 gas into organic compounds.
The carbon fixation does not involve usage of RuBisCO to form 3-PGA. This step will take place during regeneration process of Calvin cycle.
