Optimum temperature conditions for photosynthesis in `C_(3)` and `C_(4

1.	Optimum temperature conditions for photosynthesis in `C_(3)` and `C_(4)` plants are respectivelyA. `10^(@)C-25^(@)C` and `30^(@)45^(@)C`B. `30^(@)C-45^(@)C` and `10^(@)C-25^(@)C`C. `0^(@)C-10^(@)C` and `10^(@)C-30^(@)C`D. `25^(@)C-30^(@)C` and `40^(@)C-50^(@)C`.
Answer» Correct Answer - A Active site of RuBisCO for carboxylation and oxgenation is the same. The enzyme has more affinity for `CO_(2)` as compared to oxygen. Active oxygenation occurs only when `CO_(2):O_(2)` ratio favours it.
