The closing of the stomata in water-stressed rice crops initiates which metabolic alteration?

💡 Explanation

Stomata closure reduces CO2 entry, causing increased O2 buildup, therefore, favoring photorespiration because the enzyme RuBisCO binds to O2 rather than CO2; this is because CO2 availability decreases, therefore photorespiration prevails rather than C4 photosynthesis.
