• A. $N_{2} + 8e^{-} + 8H^{+} + 8ATP \rightarrow NH_{3} + H_{2} + 16ADP + 16P_{1}$
• B. $2NH_{3} + 40_{2} \rightarrow 2H^{+} + 2H_{2}O + 2NO_{3}^{-}$
• C. $N_{2} + 8e^{-} + 8H^{+} + 16ATP \rightarrow 2NH_{3} + H_{2} + 16ADP + 16P_{1}$
• D. $2NH_{3} + 3O_{2} \rightarrow 2NO_{2}^{-} + 2H^{+} + 2N_{2}O$

Answer 1

Answer: (C)

$N_{2} + 8e^{-} + 8H^{+} + 16ATP \rightarrow 2NH_{3} + H_{2} + 16ADP + 16P_{1}$
