← Nature & AnimalsWhich outcome results when a plant experiences elevated leaf temperatures combined with low CO2 concentration during daylight?
A)Increased photorespiration rate✓
B)Enhanced photosynthetic efficiency
C)Decreased chlorophyll production
D)Accelerated nitrogen fixation
💡 Explanation
When plants face high temperatures and low CO2, Rubisco, instead of facilitating carboxylation, catalyzes photorespiration by binding O2 to RuBP because higher temperatures reduce CO2 solubility, increasing O2 affinity, therefore increasing photorespiration, rather than increasing efficiency, dropping chlorophyll or accelerating nitrogen fixation, which require more nitrogen.
