Which outcome inhibits rubisco's carboxylation activity during photosynthetic reactions in plants?

💡 Explanation

When photorespiration increases in high O2 conditions, glycolate and glyoxylate concentrations rise, acting as competitive inhibitors that bind to the active site of rubisco, thus reducing CO2 fixation. Therefore, competitive binding inhibits rubisco activity, rather than magnesium deficiency, ROS accumulation or thylakoid acidification each having distinct inhibiting pathways.
