← Nature & AnimalsWhich outcome follows when water availability sharply drops within a CAM photosynthetic pathway?
A)Reduced light-independent reaction efficiency✓
B)Increased RuBisCO oxygenase activity
C)Elevated mesophyll CO2 concentration
D)Complete stomatal closure is averted
💡 Explanation
The light-independent reactions diminish because CAM photosynthesis relies on malate decarboxylation at a later time. A decline in water inhibits the initial CO2 uptake, therefore starving the Calvin cycle, rather than affecting oxygenase activity directly.
