In nitrogen fixation, we get the conversion of what to what? a, n2 to nh3 plus, b, n2 to n02 minus, c, n2 to n03 to n2, or e, nh3 plus the n2.
00:19
So what is nitrogen fixation? it's incorporating inorganic nitrogen into an organic molecule.
00:30
Instead of inorganic nitrogen, you want it to be something that you can use, for example, in amino acid or a nucleotide.
00:38
So it's not going to be starting with d or e.
00:41
Because neither would we start with one inorganic, nitrogen.
00:44
So when these are one that starts with the n2, because that's inorganic.
00:47
It's just in the atmosphere.
00:50
Which of them is it going to be? so the enzyme that does this is called a nitrogenase.
00:55
And what nitrogenase does is it reduces nitrogen.
01:03
Remember what reducing is...
