10. Which statement correctly describes carbon fixation?
a. the conversion of CO2 to an organic compound
b. the use of RuBisCO to form 3-PGA
c. the production of carbohydrate molecules from G3P
d. the formation of RuBP from G3P molecules
e. the use of ATP and NADPH to reduce CO2

c.

Explanation:

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.
