Identify the correct equation related to the mechanism of biological nitrogen fixation.
N2+8H++8e-+16ATP 2NH3+H2+16ADP+16Pi
N2+6H++8e-+12ATP 2NH4++12ADP+12pi
N2+8H++6e-+16ATP 2NH3+H2+16ADP+16pi
N2+6H++6e-+12ATP 2NH+12ADP+12pi
In biological nitrogen fixation, one molecule of nitrogen requires 8H+,8e−, and 16 ATPs to produce two molecules of ammonia.
