So the nicotine amide adenine dinucleotide is a molecule that collects electrons, which are basically abstracted from that glucose. Because remember, glucose is oxidized into Pyruvate. What that means is it loses electrons because it gains positive charge. And so those two electrons don't exist by themselves, and they're actually found on an H plus ion. So when these electrons combine with that H, we form a hydride. And so what happens is this hydride is picked up, and these electrons are picked up by this molecule here, nicotine amide and nucleotide.
