Carbon fixation occurs when CO2 combines with:

a. RuBisCo
b. G3P
c. RuBP
d. Glucose Phosphate

Answer :

Final answer:

Carbon fixation results from the combination of CO₂ and RuBP, catalyzed by the enzyme RuBisCo. The correct answer is 'c. RuBP'. The other options listed are also parts of the photosynthesis process

Explanation:

Carbon fixation is an important process in photosynthesis where the atmospheric carbon dioxide (CO₂) is converted into organic compounds. In this process, CO₂ combines with Ribulose-1,5-bisphosphate (RuBP). This process is catalyzed by the enzyme named Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as RuBisCo. Option 'c. RuBP' Is the correct answer in this context.

It's important to note that the other options in your question are part of the photosynthesis process as well. G3P (Glyceraldehyde-3-phosphate) is the molecule that is created as a result of the carbon fixation process, while glucose phosphate is part of the process of converting G3P to glucose.

Answer:

The correct answer will be option-C.

Explanation:

Carbon fixation is a step of the light-independent reaction called the Calvin cycle of the photosynthesis. The Calvin cycle proceeds in three steps: carboxylation, reduction and regeneration of RuBP.

During carboxylation, the carbon from carbon dioxide binds the RuBP molecule, a five-carbon molecule by Rubisco enzyme and form two molecules of 3-phosphoglycerate (3PGA).

Thus, Option-C is the correct answer.
