[Campbell Biology P.864] The multistep conversion of N2 to NH3 by nitrogen fixation is summa... | Practice Question

The multistep conversion of N2 to NH3 by nitrogen fixation is summarized by a specific chemical equation in the text. Which of the following is the correct equation?

  • A: N2 + 8e- + 8 H+ + 16 ATP → 2NH3 + H2 + 16 ADP + 16 Pi
  • B: N2 + 2H2O → 2NH3 + O2
  • C: NH3 + O2 → NO2- + H+ + H2O
  • D: NO3- → N2 + O2

Explanation

The text explicitly provides this equation: 'The multistep conversion of N2 to NH3 by nitrogen fixation can be summarized as follows: N2 + 8e- + 8 H+ + 16 ATP → 2NH3 + H2 + 16 ADP + 16 Pi'.
