Which compound is produced during carbon fixation?



A. PGA

B. G3P

C. RuBP

D. [tex]C_6H_{12}O_6[/tex]

Answer :

Final answer:

The compound produced during carbon fixation is G3P (glyceraldehyde-3-phosphate). It is formed when RuBP reacts with carbon dioxide during photosynthesis. G3P is essential for synthesizing glucose and other carbohydrates in plants.


Explanation:

Carbon Fixation in Photosynthesis

During the process of photosynthesis, carbon fixation refers to the conversion of carbon dioxide (CO2) into organic compounds. The primary compound produced during this stage of photosynthesis is G3P (glyceraldehyde-3-phosphate), which is crucial for the synthesis of glucose and other carbohydrates. This process takes place in the stroma of chloroplasts, where RuBP (ribulose bisphosphate) reacts with CO2 in the presence of the enzyme RuBisCO.

Here's an overview of key compounds involved:

  1. RuBP: A 5-carbon sugar that serves as the CO2 acceptor.
  2. G3P: The 3-carbon sugar produced from carbon fixation, used for synthesizing glucose.
  3. C6H12O6: Glucose, which can be formed from multiple G3P molecules later on in the process.

Overall, G3P is the direct product of carbon fixation, making it a vital player in the conversion of atmospheric CO2 into usable energy forms for plants.
