Answer:

[tex]148~ATP[/tex]

Explanation:

In case, we can start with the structure of [tex]CH_3(CH_2)_2_0CO_2H[/tex]. When we draw the molecule, we will obtain a total amount of 22 carbons. So, in order to calculate the total amount of ATP we have to make several questions:

How many Acetyl CoA is produced?

To calculate the total Acetyl Coa we have to use the equation:

[tex]Number~of~Acetyl~Coa=\frac{n}{2}[/tex], where n is the amount of carbons, so:

[tex]Number~of~Acetyl~Coa=\frac{22}{2}=11~carbons[/tex]

How many rounds take place?

To calculate the rounds we have to use the equation:

[tex]Number~of~rounds=\frac{n}{2}-1[/tex], where n is the amount of carbons, so:

[tex]Number~of~Acetyl~Coa=\frac{22}{2}-1=10~carbons[/tex]

How many [tex]FADH_2[/tex] and [tex]NADH[/tex] are produced for this fatty acid?

For each round, we will have 1 [tex]FADH_2[/tex] and 1 [tex]NADH[/tex], if we have 10 rounds. In total, we will have 10

How many ATP are formed?

The ATP would be formed in the electron transport chain and each coenzyme will have a different yield of ATP. So for the total calculation, we have to keep in mind the following relationships:

-) [tex]1~FADH_2~=~1.5~ATP [/tex]

-) [tex]1~NADH~=~2.5~ATP [/tex]

-) [tex]Acetyl~CoA~=~10~ATP[/tex]

So, know we can do the total calculation:

[tex](10*1.5)+(10*2.5)+(11*10)=150[/tex]

We have to subtract  "2 ATP" molecules that correspond to the activation of the fatty acid, so:

[tex]150-2=148~ATP[/tex]

In total, we will have 148 ATP.

See figure 1

I hope it helps!
