Okay, i'm going to answer this question.
00:01
I'll have to talk about the complete breakdown of one glucose molecule.
00:06
First, we're going to start with glucose, with one glucose molecule, and it is going to be broken down into the end product of this process that are practically two pyruvate molecules.
00:23
This process is called glycolysis, and it occurs in the cytosol of the cell.
00:31
Okay, during this process, there is use of two atps, one here and another one here.
00:42
And there is production of one atp here, another atp here, and the same.
00:49
I got the other side.
00:51
Okay.
00:52
Also, there is production of one nadh per site.
01:02
So you have a total production of minus 280ps.
01:07
Well first let's calculate the total plus the 1 2 3 4 8ps plus 2 n80s plus 2 n80s molecules okay so here we're going to have a total production of 2 atps plus 2 n80s molecules remember that the n a dh molecules have to go to the electron transport chain to produce atp okay let's leave it like this and later we're going to come back here so the next process is called pyruvate oxidation that occurs in mitochondria and there is production of one acetyl co -a per pyruvate molecule and there is production of one an adhd per side okay and so we here we're going to have practically two an adhd molecules produced and finally each acetal coa molecule is going to enter the krebs cycle that occurs also in mitochondria and this in this crept cycle, each cycle, okay, because we have two cycles here, each cycle is going to produce 3 nadh, 1 fadh 2, and 1 atp.
02:36
The same here in the other cycle.
02:43
So, practically, in total, you're producing here 6 nadh molecules plus 2fadh plus 280ps.
02:58
Okay, now the classic equivalence says that one nadh molecule produces three atps in the electron transport chain and one fadh2 molecule produces two atps.
03:19
Okay, so let's use this classic equivalence in order to calculate the levels of atp here in pyrobed oxidation and grape cycle...
