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

💡 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.
