Sample questions
The action spectrum of photosynthesis is shown. The two peaks and the "green gap" (minimum near 550 nm) are explained by:
Assertion (A): C4 plants are more efficient in photosynthesis than C3 plants in hot, dry conditions. Reason (R): PEP carboxylase in C4 plants has a higher affinity for $\ce{CO2}$ than RuBisCO, minimizing photorespiration.
In C4 plants, the primary $\text{CO}_2$ acceptor and the enzyme responsible for its initial fixation are respectively:
