← Nature & AnimalsWhich event follows exceeding Rubisco capacity in C4 plants?
A)Photorespiration rate diminishes greatly✓
B)Stomata immediately fully open wider
C)Malate production pathway shuts down
D)Increased rate of oxygen production
💡 Explanation
When C4 plants experience Rubisco saturation, photorespiration decreases greatly because C4 pathways concentrate CO2, therefore photorespiration is suppressed, rather than stomata and oxygen production increasing or malate production ceasing immediately from excessive CO2 alone.
