Question

Quizplus · Accepted Answer

The reduction of molecular nitrogen is a process known as nitrogen fixation, which is carried out by nitrogen-fixing bacteria. In these bacteria, the electrons for the reduction of N2 are donated by ferredoxin. Neither proteins nor NADPH donate electrons for the reduction of N2. Therefore, option A and B are incorrect. Option D is also incorrect because at least one of the options should be correct. Thus, the correct answer is C, ferredoxin.
