Which risk increases when soil salinity inhibits photorespiration?

💡 Explanation

Increased soil salinity inhibits photorespiration that normally detoxifies glycolate; the rubisco enzyme catalyzes oxygenation rather than carboxylation because high salt stress causes stomatal closure. Therefore, toxic glycolate accumulates, rather than being converted into glycerate via photorespiration under optimal carbon fixation conditions.
