Which effect occurs when high oxygen concentration competitively inhibits Rubisco in C3 plants?

💡 Explanation

When high oxygen concentration is presented, photorespiration outcompetes carbon fixation because Rubisco has a higher affinity to carbon dioxide as substrate than to oxygen, so it acts as an oxygenase rather than a carboxylase. Therefore, increased photorespiration results, rather than carbon fixation, water uptake, or nitrogen uptake.
