activation consumes one ATP, 12 carbon splits 5 times, each beta oxidation 5 ATP
the answer is correct okt3 bye I am singing off now

i am not good in math but (5x5-1)+ 6x12 is not 95

gemin121 look at this one if you are still arround

I agree, not good at math, as i used 5 atps total, went for 95 apprx

[ArchivalUser]

well if you have 95 and 97, and your calcul. is 96, it is hard to choose 95 or 97.

u have mentioned 2 atp, isnt it 1 atp

[ArchivalUser]

C. 95 ATP total:
1) 12 carbones gives us 6Acetyl COA*12=72
2) 5NADH*3=15
3) 5FADH*2=10
4) 72+15+10-2=95

The correct answer is C.
Activation of the laurate requires two high-energy phosphate bonds as ATP is converted to AMP.
The 12 carbon lauryl CoA is then split 5 times to produce 6 acetyl CoAs, and 5 ATPs (obtained from 1 FADH2 and 1 NADH), that are produced by each β-oxidation cycle.
The resulting 6 acetyl CoA each produce 12 ATP

If you know the concept 2n=number of C, n-1=(NAD, FAD), n=Acetyl-Coa, you are all set to do the math for any even carbon FA oxidatio.

Dont know for un-even carbon.

cingular, I posted for you to see if you got the concept, good job and

Thanks All for input.

I got it OKT3, THANKS a lot! Great explanation! I forget that Qbank has that q...
