← Nature & AnimalsWhich limitation is directly imposed on photosynthetic rate when increased temperatures reduce rubisco's specificity?
A)Photorespiration generates carbon dioxide byproduct✓
B)Chlorophyll degrades forming less photosystems
C)Stomata closes to limit transpirational losses
D)Thylakoid membrane damage inhibits electron transport
💡 Explanation
When temperatures increase, rubisco's specificity decreases because it binds more readily with oxygen instead of carbon dioxide, resulting in greater rates of photorespiration, where carbon dioxide is produced rather than fixed. Therefore, increased temp imposes increases a higher carbon dioxide byproduct instead of other mechanisms which do not involve rubisco.
