Which 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.
