So in this question, we are looking at the aerobic metabolism of glucose or c6 h12 .o6.
00:08
And these are the basic reactions to pretty much all of life.
00:12
The cells need cellular respiration to be carried out in order to generate oxygen and overall fuel and atp for the cell.
00:23
So essentially, while this question is asking us, how many atp molecules can be made from the complete aerobic metabolism of one.
00:31
Molecule of glucose and this is going to incorporate all of our steps.
00:35
So glycolysis, the acetyl pathway, or the entrance pathway into the krebs cycle, also known as the tca cycle, and then our electron transport chain, which is our oxidative phosphorylation phase, and that's going to be our big generator of atp in the end.
00:52
So i figured the best way to go about doing this for one molecule of glucose is just to go through all of our main step pathways.
01:01
And take note of our inputs and outputs because our outputs are essentially what is going to then be transported to our final electron transport chain and be used in oxidated phosphorylation to create kind of our mass production of atp.
01:17
So starting off with glycolysis and our glycolysis is going to take place in our cytoplasm.
01:25
And for inputs, we are going to have two atp.
01:29
So this is going to be our energy investment phase.
01:33
We're going to have 4 adp, which is going to form some of our atp molecules and our outputs, which i will get to.
01:42
We're going to have 2 nad plus, and nad plus is going to be one of our high electron carriers once it is reduced.
01:53
And obviously, most importantly, we need one molecule of glucose.
01:58
So for our outputs of this, we are going to wind up with 4 atp.
02:06
And because we use 2 atp, most people say 2 net atp, since there is an energy investment phase.
02:15
We're going to have 2nath plus.
02:19
And like i said, those are our high electron carriers, which are going to be transported directly to the electron transport chain.
02:26
And two pyruvate molecules which are necessary in order to enter the crept cycle and in our acetyl -coa pathway.
02:35
So pyruvate is essential to continue the process of this aerobic metabolism.
02:41
So entering into our acetylcoa pathway, also known as pre -creb cycle, a lot of our outputs are going to be directly put in as inputs.
02:51
You'll see that theme.
02:52
So for inputs, we're going to have our two pyruvate molecules from glycolysis...
