Which outcome occurs when abnormally high temperatures inhibit Rubisco activation in C3 plants?

💡 Explanation

When high temps inhibit Rubisco activase, Rubisco's carbon-fixation activity decreases because it cannot maintain its active conformation, resulting in increased photorespiration instead of photosynthesis due to oxygen binding. Therefore photorespiration surpasses photosynthesis rather than enhancing starch yield, ATP synthesis, or enabling greater nitrogen assimilation, which are independent processes.
