Which mechanism shifts photosynthetic pathways when aquatic plant environments experience acidification?

💡 Explanation

C4 photosynthesis provides a mechanism that concentrates CO2 around Rubisco, which becomes especially important under acidified conditions; therefore, C4 utilization increases carbon fixation because photorespiration is less favorable at high CO2, rather than other normal respiration increases.
