Which risk increases when mesophyll photosynthesis rate limits sugar production?

💡 Explanation

Photorespiration increases because high O₂/CO₂ ratios trigger RuBisCO oxygenation rather than carboxylation. Therefore, photosynthetic quantum yield decreases, rather than RuBisCO binding improving or CAM upregulation accelerating.
