Which risk increases when aquatic plants rely solely on CO2 assimilation via photorespiration?

💡 Explanation

When photorespiration occurs, the enzyme RuBisCO binds O2 instead of CO2, leading to the production of 2-phosphoglycolate, which must get processed, generating reactive oxygen species and oxidative stress because the carbon fixation efficiency declines. Therefore an increased risk of oxidative stress results, rather than heightened immunity, nitrogen fixation, or nutrient absorption which depend on different metabolic pathways.
