Given arid conditions, which outcome occurs when photorespiration accelerates via rubisco?

💡 Explanation

Increased photorespiration, occurring through Rubisco's oxygenase activity rather than carboxylase, reduces photosynthetic efficiency because fixed carbon is lost via the photorespiratory pathway. This favors enhanced CO₂ uptake utilizing alternative carbon fixation methods, therefore avoiding photorespiration rather than enabling greater photosynthesis in C3 plants.
