Which metabolic consequence arises when high temperatures trigger widespread stomata closure in C4 plants?

💡 Explanation

When stomata close due to high temperatures, CO2 concentration decreases within the leaf, causing O2 accumulation, favouring photorespiration over carboxylation in mesophyll and indirectly affecting overall carbon fixation. Therefore, photorespiration increases, rather than carbon fixation, oxygen diffusion increase, or PEP carboxylase activity reduction which are independent process factors.
