Which photosynthetic inefficiency arises when desert plants overheat?

💡 Explanation

Increased temperatures cause photorespiration because rubisco binds more readily to O₂ rather than CO₂, therefore carbon fixation decreases dramatically, rather than the breakdown of the electron transport chain slowing carbon production.
