← Nature & AnimalsWhich photosynthetic outcome occurs when a CAM plant's store of malic acid is depleted?
A)Photorespiration rate increases rapidly
B)Carbon fixation rate drops significantly✓
C)Stomata remain closed indefinitely
D)Chloroplasts enter a dormant state
💡 Explanation
When malic acid is depleted, the Calvin cycle runs short of CO2, because this acid normally releases CO2, and this reduction lessens the carbon fixation activity. Therefore, fixation decreases, rather than higher photorespiration, closed stomata or dormant chloroplasts each require different physiological triggers.
