Which risk increases when elevated leaf temperature inhibits Rubisco's carboxylation efficiency in C3 plants?

💡 Explanation

When Rubisco's carboxylation declines due to heat, photorespiration rises because Rubisco binds more oxygen relative to carbon dioxide, leading to carbon loss. Therefore photorespiration increases rather than altered Nitrogen fixation, transpiration rates or xylem conditions which depend on different constraints or biochemical pathways.
