Calvin Cycle - Carboxylation
-
Which of the following statements about RuBisCO is true?
RuBisCO catalyzes the carboxylation of ribulose-1,5-bisphosphate (RuBP) in the Calvin cycle.
RuBisCO (RuBP carboxylase-oxygenase) catalyzes the crucial initial carbon-fixing step: carboxylation of RuBP with $CO_2$ to form two molecules of 3-PGA. It has higher affinity for $CO_2$ than $O_2$ under normal atmospheric ratios.
Photosynthetic Pigments

Match List-I with List-II.
Pick the matching item from Column II for each row.
Column I
- A. Chlorophyll a
- B. Chlorophyll b
- C. Xanthophylls
- D. Carotenoids
Column II
- I. Yellow-green
- II. Yellow
- III. Blue-green
- IV. Yellow to Yellow-orange
Correct answer: A → III, B → I, C → II, D → IV
A-III, B-I, C-II, D-IV.
Chromatographic colors of leaf pigments: Chlorophyll a is blue-green (III), Chlorophyll b is yellow-green (I), Xanthophylls are yellow (II), and Carotenoids range from yellow to yellow-orange (IV).
