प्रश्न
Answer the following question.
In C-4 plants, why is C-3 pathway operated in bundle sheath cells only?
उत्तर
- Decarboxylation of malic acid occurs in bundle sheath cells of C4 plants. Due to which concentration of CO2 increases in bundle sheath cells.
- The enzymes required for the Calvin cycle i.e. RuBisCO are present in bundle sheath cells.
- In presence of a high concentration of CO2, RuBisCO acts as a carboxylase and brings about carboxylation of RuBP. Hence, in C-4 plants, C-3 pathway is operated in bundle sheath cells only.
