Match List I with List II :

Which of the following statements about RuBisCO is true?

Which of the following are required for the dark reaction of photosynthesis? A. Light B. Chlorophyll C. CO₂ D. ATP E. NADPH Choose the correct answer from the options given below:

How many molecules of ATP and NADPH are required for every molecule of CO₂ fixed in the Calvin cycle?

Given below are two statements: Statement I: In C₃ plants, some O₂ binds to RuBisCO, hence CO₂ fixation is decreased. Statement II: In C₄ plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration. In the light of the above statements, choose the correct answer from the options given below:
