The complete oxidation of palmitate to gives 08 acetyl coa, 7FADH and 7NADPH so 96 ATP from acetyl coa,14 ATP from FADH and 21 ATP FROM NADPH But 2 ATP WAS CONSUMED.

Palmitic acid (16-C).
7 B-oxidation.
- 7 FADH2 = 14 ATP.
-7 NADH = 21 ATP.
-8 Acetyl CoA = 96 ATP.
Total = 131.

2 ATPs by activation step.

Net ATP : 131-2 = 129 ATP.

This answer is not making sense to me? Can you please explain more detail?

What is B-oxidation?

Abdullah said: (Feb 7, 2015)  
Where the consumption occur? This is not clear.

Celiwe said: (Oct 11, 2016)  
When the question says a complete oxidation, that involves TCA cycle? I am confused, please help me.

B-oxidation is a very important part of fatty acid degradation which occurs in the mitochondrial matrix. It is the conversion of carnitate into acyl CoA which ultimately through a series of reactions produce acetyl CoA as well as Acyl CoA.

Each fadh2 generates 1, 5 ATP. NADH H generates 2. 5 ATP. The correct answer is 108-2 is 106. 2 atp used in activation.

Monalisha said: (May 6, 2017)  
Yes, @Feruza.

It's 106 only.

John said: (Nov 9, 2017)  
You are right @Feruza.

Palmitate has 16 carbons.

Acetyl coA=16/2 * 12ATP = 96ATP.
Number of rounds =7 i.e. no of carbon/2 -1.
2FADH * 7 = 14.
3NADH *7 = 21.

96+14+21=131 - no of ATP used up during activation of fatty acid by co ASH, 2 =129.
