← Nature & AnimalsWhich photosynthetic inefficiency arises when desert plants overheat?
A)Photorespiration surpasses carbon fixation✓
B)Electron transport chain shuts down
C)Chlorophyll synthesis rate declines
D)Stomata completely close indefinitely
💡 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.
