Answer :
Final answer:
During carbon fixation, the compound specifically produced is G3P (glyceraldehyde-3-phosphate). While PGA is an intermediate and RuBP is involved in the process, C6H12O6 (glucose) is not directly a product of carbon fixation. G3P is essential for synthesizing glucose and other carbohydrates.
Explanation:
Understanding Carbon Fixation
In the process of photosynthesis, particularly during the Calvin Cycle, carbon fixation occurs, which refers to the incorporation of carbon dioxide into organic compounds. The main product of this process is G3P (glyceraldehyde-3-phosphate), which is a three-carbon sugar that plays a crucial role in the synthesis of glucose and other carbohydrates.
To clarify the other options mentioned:
- PGA (3-phosphoglycerate) is also produced during carbon fixation, but it is an intermediate product formed from RuBP after it reacts with CO2.
- RuBP (ribulose bisphosphate) is a five-carbon compound that acts as a substrate for the enzyme RuBisCO and begins the process of fixing carbon dioxide.
- C6H12O6 (glucose) is a product of the overall photosynthesis process, but it is not directly the outcome of carbon fixation in the Calvin cycle.
Thus, the compound specifically produced during carbon fixation is G3P.
