00:13
So that's basically asking why is oxygen needed, i .e.
00:17
Why do we need to breathe oxygen? why do we need oxygen? so let's start with real quickly.
00:27

01:03
Part.
01:05
It is nadh and f .a .d .h.
01:10
2.
01:12
Now, let's draw the membrane of a mitochondria here.
01:20
The nadh and the fadh2 get transported into the mitochondria...
