← ScienceWhich outcome arises for nitrogenase when catalytic electron transfer decreases?
A)Substrate-binding sites become less occupied
B)Magnesium-ATP hydrolysis activity increases
C)Nitrogen reduction activity is limited✓
D)Iron protein conformational changes accelerate
💡 Explanation
Limited electron transfer decreases nitrogenase nitrogen reduction activity because the **nitrogenase mechanism** requires several electron transfer steps from the Fe protein to ultimately reduce N2; therefore, nitrogen reduction is limited, rather than magnesium-ATP activity increasing under electron scarcity.
