In order to answer this question, let's talk about bit oxidation.
00:03
It says how much atp can be produced from a saturated fatty acid that contains 20 carbons.
00:10
So you have 20 carbons here.
00:14
Now, remember that when you have a fatty acid here, let's suppose, well, in this case you have 20 carbons, okay? 20 carbons.
00:28
So in each ground of bit oxidation, you're going to lose or you're going to produce one in the age, 1 fadh2, and one acetylch.
00:40
This acetal coa is made of 2 carbons, and this is because in each ground you're going to lose 2 carbons, and you're going to have a remaining of 18 carbons.
00:50
Okay, and so on.
00:51
So this is what is going to happen here.
00:53
So after how many cycles you're going to have a remaining of 4 carbons? after, if you have, for example, 8 rounds of beta oxidation, after after 8, 8 ,000, rounds you're going to produce 8 nadh, 8 fadh 2, 8 acetalcoid molecules, and you're going to have a remaining of, as each acetalcoy molecule has 2 carbons, 2 multiplied 8 is equal to 16.
01:26
So you have lost 16 carbons, and as you had initially 20 carbons, then you're going to have a remaining of 4 carbons.
01:36
When you have 4 carbons, then you have 4 carbons, ground is going to be the last one because when you split your molecule for these two carbons to convert into acetal co -8 you also have a remaining of two carbons more so these are going to these two carbons are also in the same reaction going to be lost as acetal coa so in this case you're going to produce one more an adh one more faddh too like this nine nine and two acetal coi molecules one here and another here so you're going to have 10 acetal coaid molecule these two acetyl -coid molecules only are produced in the last reaction, okay? so this is what you have.
02:17
Now, each nadh produces 2 .580ps, so you have to multiply 2 .5 by 9 and this is equal to 22 .580ps...
