Which outcome occurs when a plant experiences excessive photorespiration due to sustained high oxygen level around rubisco?

💡 Explanation

When oxygen levels are high relative to carbon dioxide, rubisco catalyzes photorespiration because it binds with oxygen instead of CO2, leading to a wasteful cycle that consumes ATP and NADPH without producing sugar. Therefore reduced carbohydrate production develops, not enhanced chlorophyll, modified protein biosynthesis or water absorbtion rates.
