00:01
Okay, we want to answer this question.
00:01
Let's talk about aerobic exploration.
00:03
It says for the following field in the requested number of molecules given the information provide, use numerical delete for this answer.
00:11
So let's go for question a.
00:14
It says three glucose molecules undergoing glycolysis only, only glycolysis, okay? how many atp is produced by substrate levels of fluoridation? remember that you're going to start a lycolysis with a glucose molecule and you're going to have like practically two stages of glycolysis.
00:30
The final products are going to be part of it.
00:33
Here you're going to produce an adh, but an adh is going to provide atp by osiative for correlation, but not by substrate level of fluoridation.
00:42
So let's focus only on substrate levels of fluoridation.
00:45
So here you're going to use two atps, one atp and another atp.
00:53
But in the second step of localization, you're going to produce 1 atp, 1 atp, and the same here, 1 atp and another atp.
01:05
So you're going to produce 4 adps, but you're going to use 2 atp.
01:08
So you have a net product of 2 atp.
01:11
But this question is not asking us for the net atp synthesis.
01:16
It is asking us for only by the number of atps that you're going to produce by certain levels of fluoridation in glycolysis.
01:25
So you have 4.
01:27
Okay, they are not asking you for the net atp synthesis.
01:30
Because if they ask you for the net atp synthesis, then you would have to subtract this 4 by 2.
01:36
Okay? so, they are asking you, so practically per one glucose molecule you're going to produce 480ps.
01:43
So if you have three glucose molecules, then you're going to produce 12 atp's.
01:51
Four perin glucose molecule.
01:52
Remember that they are not asking you for the net atp indices.
01:56
If they would ask you for the net atp, then you would have three glucose molecules multiply by 2, and it would be 6.
02:03
Okay, so maybe you can ask your teacher about this question if they refer to the net atp synthesis or only to those atp that are being synthesized by certain level of population.
02:16
Question b says six glucose molecules undergoing glycolysis and pyrobin oxidation, how many nadh molecules are produced? so here in the second step of glycolysis you're going to produce nadh here and another nadh here.
02:35
So you have two nadh molecules per side.
02:39
Okay.
02:40
And also after pyruvate oxidation, it involves practically a conversion of pyruvate to acetyl co -a.
02:47
And in each of these reactions we're going to produce an adhd and adhd.
02:53
So per glucose molecule, you're going to produce one, two, three, and four in adhd.
02:58
So one glucose molecule is going to produce four in adhd molecules.
03:04
So if you have six glucose molecules, then you're going to produce 24 in adh.
03:11
Okay, so this is what you're going to have for this question b, okay? because we're considering these two pyruid molecules that glucose is producing, and each of them are going to go, are going to undergo this process of pyrobed oxidation.
03:26
And now let's go for the next question, question c, that says, five glucose molecules undergoing glycolysis and pyrobed oxidation, how many atp produced via substrate levels of foliation, about osteitis of correlation total.
03:39
So this is actually a for the net atp.
03:43
So here only talking about substrate level of fluoridation, you're going to have 480ps minus 280ps because we're talking about the net production, okay? so you have a total of 280ps plus 2naids molecules, only in glycolysis, okay? we're talking only in glycolysis.
04:00
Now, this, this nadh molecules that are produced in glycolysis, it occurs in the cytoplasen, remember.
04:08
So this nadh cannot possibly get into mitochondria in order to to be exchanged by atp.
04:16
Okay, so nadh is going to require charles in order to get into mitochondria into the electron transport chain and then produce atp via ossetoforillation.
04:23
So it can use this glycerol -thryphosphate shuttle or it can use the malate aspartate shuttle...
