← Nature & AnimalsWhich consequence results when PEP carboxylase outcompetes RuBisCO?
A)Photorespiration increase in the mesophyll
B)Carbon fixation reduced to zero
C)Efficient carbon capture in hot climates✓
D)Stomata open at night to prevent damage
💡 Explanation
Efficient carbon capture in hot climates occurs because PEP carboxylase's higher affinity for CO₂ facilitates C4 and CAM pathways, creating a spatial separation, therefore minimizing photorespiration, rather than increasing it because RuBisCO struggles with oxygenation at high temperatures.
