Why Is Photorespiration More Likely to Occur in Warm Weather

Multiple Choice

Why is photorespiration more likely to occur in warm weather?

A) Plants require warm weather (at least 23°C) to drive photosynthesis.
B) Plants are more likely to close their stomata in the daytime heat than at night when it is cool.
C) Plants are more likely to dehydrate in warm weather, forcing them to close their stomata to conserve water; this prevents CO₂ from entering the leaf.
D) The rubisco enzyme is very temperature-sensitive and becomes less selective in warmer temperatures, allowing it to fix O₂ instead of CO₂.
