Which metabolic shift results when photorespiration depletes RuBP?

💡 Explanation

Reduced carbon fixation efficiency occurs because the **oxygenase activity** of rubisco leads to RuBP depletion when CO2 is low; therefore carbon fixation decreases, rather than cycling electrons because energy is not limited or shifting the photosynthetic pathway which requires genetic specialization.
