Stages of Calvin Cycle Details A. Regeneration 1. Fixation of CO2 into a stable organic intermediate; catalyzed by RuBisCO. B. Reduction 2. Involves the use of ATP and NADPH to convert 3-PGA into glyceraldehyde-3-phosphate (G3P). C. Carboxylation 3. Regeneration of RuBP from G3P to enable the cycle to continue. D. RuBisCO 4. Enzyme that catalyzes the fixation of CO2 and also has oxygenation activity.
Options
- AA - 3, B - 2, C - 1, D - 4
- BA - 4, B - 3, C - 2, D - 1
- CA - 2, B - 1, C - 4, D - 3
- DA - 3, B - 4, C - 1, D - 2
Correct answer
A. A - 3, B - 2, C - 1, D - 4
Step-by-step solution
A - .3: Regeneration involves the conversion of G3P back to RuBP to continue the cycle. B - 2: Reduction involves the use of ATP and NADPH to convert 3-PGA into glyceraldehyde-3-phosphate (G3P). C - 1: Carboxylation involves the fixation of CO2 into a stable organic intermediate, catalyzed by RuBisCO D - 4: RuBisCO is the enzyme that catalyzes the fixation of CO2 and has oxygenation activity.
