Which outcome results when plants with C4 photosynthesis experience thermal stress?

💡 Explanation

Rubisco’s affinity for oxygen increases with higher temperatures leading to photorespiration; the carboxylation efficiency decreases because thermal stress favors oxygenation, therefore, photorespiration increases rather than decreases, hindering efficient carbon fixation at high temperatures.
