Which risk decreases when a C4 plant elevates CO2 concentration near Rubisco in bundle sheath cells?

💡 Explanation

When C4 plants concentrate CO2 near Rubisco, efficiency increases because the high CO2 concentration outcompetes oxygen binding the active site, minimizing photorespiration's wasteful reactions. Therefore photorespiration drops, rather than influencing water loss, ATP usage or nitrogen deficiencies which depend on stomatal control, Calvin cycle and protein biosynthesis independently.
