Correct answer is (b) N2 +8e-+8H++16ATP → 2NH3+H2+16ADP+16P1

Q. Which one is the correct summary equation of nitrogen fixation ?

$N_{2} + 8 e^{-} + 8 H^{+} + 8 A TP \to$ $N H_{3} + H_{2} + 16 A D P + 16 P_{1}$

$N_{2} + 8 e^{-} + 8 H^{+} + 16 A TP \to$ $2 N H_{3} + H_{2} + 16 A D P + 16 P_{1}$

$2 N H_{3} + 4 O_{2} \to 2 H^{+} + 2 H_{2} O + 2 N O_{3}^{-}$

$2 N H_{3} + 3 O_{2} \to 2 N O_{2}^{-} + 2 H^{+} + 2 N_{2} O$

Correct answer is (b) $N_{2} + 8 e^{-} + 8 H^{+} + 16 A TP \to$ $2 N H_{3} + H_{2} + 16 A D P + 16 P_{1}$

Q. Which one is the correct summary equation of nitrogen fixation ?

N2​+8e−+8H++8ATP→ NH3​+H2​+16ADP+16P1​

N2​+8e−+8H++16ATP→ 2NH3​+H2​+16ADP+16P1​

2NH3​+4O2​→2H++2H2​O+2NO3−​

2NH3​+3O2​→2NO2−​+2H++2N2​O

Correct answer is (b) N2​+8e−+8H++16ATP→ 2NH3​+H2​+16ADP+16P1​

$N_{2} + 8 e^{-} + 8 H^{+} + 8 A TP \to$ $N H_{3} + H_{2} + 16 A D P + 16 P_{1}$

$N_{2} + 8 e^{-} + 8 H^{+} + 16 A TP \to$ $2 N H_{3} + H_{2} + 16 A D P + 16 P_{1}$

$2 N H_{3} + 4 O_{2} \to 2 H^{+} + 2 H_{2} O + 2 N O_{3}^{-}$

$2 N H_{3} + 3 O_{2} \to 2 N O_{2}^{-} + 2 H^{+} + 2 N_{2} O$

Correct answer is (b) $N_{2} + 8 e^{-} + 8 H^{+} + 16 A TP \to$ $2 N H_{3} + H_{2} + 16 A D P + 16 P_{1}$
