Which outcome affects C3 plant growth when excessive ozone inhibits Rubisco activase?

A)Reduced photosynthetic efficiency overall
B)Increased photorespiration by stomatal closure
C)Enhanced nitrogen fixation in root nodules
D)Accelerated translocation due to higher turgor

💡 Explanation

When ozone inhibits Rubisco activase, Rubisco's carboxylation activity decreases because Rubisco needs activase to remove inhibitory sugar phosphates blocking its active sites, decreasing photosynthesis. Therefore, reduced efficiency impacts growth, rather than photorespiration, N-fixation, or translocation which have different control processes.
