Which consequence results when a plant experiences prolonged high-temperature stress impacting Rubisco function?

💡 Explanation

Under high-temperature stress, Rubisco's affinity for O2 increases reducing CO2 fixation due to competitive inhibition in the Calvin cycle, stimulating oxygenase activity. Therefore increased photorespiration (producing CO2 and consuming ATP) results, rather than chlorophyll increases, accelerated root development, or improved water efficiency, which require different environmental interactions.
