Answer:
94 ATP molecules
Explanation:
To answer the question we need to understand the beta oxidation of fatty acid.
- First we need to know each electron carrier produces different number of ATP molecules in the electron transport chain.
- That is, FADH₂ yields 1.5 ATP while NADH yields 2.5 ATP molecules
- Additionally, for every acetyl coA, 10 ATP molecules are produced.
What happens during oxidation of a fatty acid with even number of carbon, C₂ₙ?
- During beta oxidation of an even number fatty acid, C₂ₙ, n-1 FADH₂, n-1 NADH and n acetyl coA molecules are produced.
- Therefore, for a fatty acid with 14 carbons, then 6 molecules of FADH₂, 6 molecules of NADH and 7 acetyl coA are produced.
- Therefore, the number of ATP molecules will be;
From; 6 FADH₂ = 6 × 1.5 = 9 ATP
6 NADH; 6 × 2.5 = 15 ATP
7 Acetly CoA ; 7 × 10 = 70 ATP
This gives a total of 94 ATP molecules
Hence a 14 carbon fatty acid produces 94 ATP molecules after beta oxidation.
A 14 Carbon fatty acid has 94 ATP molecules.
Before answering this question we need to learn the ATP yield for every oxidation cycle which is:
- FADH₂ produces 1.5 ATP while NADH yields 2.5 ATP molecules and for every acetyl CoA, 10 ATP molecules are produced.
Beta Oxidation of Fatty Acid:
- In beta-oxidation fatty acid molecules breaks down via catabolic process. During β-oxidation for even numbered fatty acid one molecule of FADH₂, NADH and acetyl CoA are formed.
- Fatty acid containing 14 carbon atoms produces 6 molecules of FADH₂, 6 molecules of NADH and 7 molecules of acetyl CoA.
So for the calculation of ATP molecules:
6 FADH₂ =6×1.5=9 ATP
6 NADH=6×2.5=15 ATP
7 acetyl CoA=7×10=70 ATP
Total number of ATP molecules are 94.
Therefore, a 14 carbon fatty acid produces 94 ATP molecules.
