Which consequence results when increasing leaf temperature compromises mangrove rubisco?

A)Optimized photorespiration for carbohydrate production
B)Reduced carbon fixation into sugars
C)Enhanced water transport through xylem
D)Improved nitrogen assimilation efficiency

💡 Explanation

Increased leaf temperature raises oxygen affinity relative to carbon dioxide for rubisco, leading to increased photorespiration. Consequentially, decreased carboxylation via the carbon fixation mechanism results, therefore the photosynthetic rate declines and the production of sugars is limited, rather than increased photorespiration optimizing carbohydrate output.
