Which outcome occurs when high oxygen concentrations inhibit rubisco’s carboxylation activity?

💡 Explanation

When high oxygen levels inhibit rubisco, photorespiration increases because rubisco catalyzes oxygen fixation instead of carbon dioxide, leading to a net loss of energy and carbon. Therefore photorespiration increases, rather than suppressed CAM, wider stomata, or accelerated chlorophyll synthesis, which depend on different environmental cues.
