← Nature & AnimalsWhich process dictates higher plant nitrate reduction affinity?
A)Increased symbiotic gut bacteria count
B)Enhanced root surface plasmodesmata number
C)Elevated limiting soil nitrogen availability✓
D)Decreased leaf stomatal conductance
💡 Explanation
Nitrate reductase affinity increases alongside nitrogen scarcity via metabolic acclimation, because greater enzyme activity is more advantageous. Enzyme induction is the mechanism driving affinity increase; therefore, limited nutrients favor a higher affinity rather than other transport adaptations
