ā Nature & AnimalsWhich outcome occurs when nitrogenase is inhibited in Rhizobium bacteria?
A)Reduced photosynthate transport to roots
B)Decreased ammonia production in nodulesā
C)Enhanced ATP synthesis in bacteroids
D)Increased methane production in plant
š” Explanation
Inhibition of nitrogenase prevents dinitrogen fixation because nitrogenase catalyzes the reduction of Nā to ammonia; therefore, ammonia production decreases, rather than changes in ATP, transport, or methane.
