This question asks us to describe the step -by -step process by which electrons from glucose catabolism into cytoplasm are transferred to the electron transport chain in the inner mitochondrial membrane.
00:11
In our answer, we will note whether or not the electron transfer at each step is going to be direct or indirect.
00:19
So, to start off, where are these electrons coming from? well, as we know, glycolysis will deposit electrons, so actually we'll write this down.
00:32
Will deposit electrons giving them to nad plus.
00:40
So the electrons will be donated to nad plus, so the electrons will come from here.
00:46
It will actually come from glycolysis, so actually, glycolysis will deposit electrons on nad plus.
00:53
Also, we will combine it with a hydrogen atom.
00:57
And what we'll see is our nad plus becomes nadh when this electron transfer occurs.
01:05
And this electron transfer is going to be direct, right? because we're taking the electrons from glycolysis when we're depositing them directly onto nad plus.
01:18
So now we have nadh, and the electron is going to be on nadh.
01:24
So now nadh will move from the cytosol, because remember, this right here occurs in the cytosol of the cell...
