Which outcome is observed when high temperatures inhibit plant Rubisco's enzyme activity during photosynthesis?

💡 Explanation

When high temps inhibit Rubisco function, the carboxylase activity decreases because the enzyme's active site is less efficient, directly leading to a reduced rate of carbon dioxide fixation in the Calvin cycle. Therefore carbon dioxide fixation decreases, rather than ATP production increase, oxygen enhancement, or chlorophyll synthesis which are not directly controlled by Rubisco's carboxylation activity.
