Which consequence results when Rubisco malfunctions in C4 photosynthetic pathways?

💡 Explanation

When Rubisco malfunctions in C4 plants, the intended CO2 concentrating mechanism fails because CO2 fixation efficiency drops, leading to increased binding of O2 and thus significantly higher photorespiration. Therefore photorespiration increases, rather than triggering CAM shift or accelerating synthesis because these require different metabolic adjustments.
