Assertion: In `C_(4)` plants, photorespiration does not occurs. Reason: `C_(4)` plants have a mechanism that increaes the concentration of `CO_(2)` at the enzyme site. |

Answer» Correct Answer - A In `C_(4)` platns photorespiration does not occur because they have a mechanism that increaes the concentration of `CO_(2)` at the enzyme site. This takes place when the `C_(4)` acid from the mesophyll is broken down in the bundle sheat cells to relaase `CO_(2)`. this results in increasing the intracellular concentration of `CO_(2)`. This ensures that the RuBisCO functions as a carboxylase. Thus. minimising the oxygenase activity. |
