How much ATP is formed by the complete catabolism of a 12 carbon fatty acid?
ATP Yield from Fatty Acid Oxidation
| 1 mol of ATP is split to AMP and 2Pi | −2 ATP |
|---|---|
| 8 mol of acetyl-CoA formed (8 × 12) | 96 ATP |
| 7 mol of FADH2 formed (7 × 2) | 14 ATP |
| 7 mol of NADH formed (7 × 3) | 21 ATP |
| Total | 129 ATP |
How many ATP are produced from the complete oxidation of lauric acid a 12 carbon FA?
95 mol
_____ TOTAL: Net ATP from three steps above. 1 mol of glucose (180 g) generates 38 mol of ATP. 1 mol of lauric acid (12:0, 200 g) generates 95 mol of ATP.
How many ATP are produced per fatty acid?
Complete oxidation of one palmitate molecule (fatty acid containing 16 carbons) generates 129 ATP molecules.
How many ATPS are produced by acetyl CoA from the oxidation of a 12 carbon fatty acid?
12 ATP
Theoretically ATP yield for every oxidation cycle can be maximum upto 17, as NADH produces 3 ATP, FADH2 = 2 and end product, acetyl COA governed Citric Acid Cycle produces 12 ATP.
How many ATP can be generated from a 14 carbon chain fatty acid?
In addition, two equivalents of ATP are lost during the activation of the fatty acid. Therefore, the total ATP yield can be stated as: (0.5 * n – 1) * 14 + 10 – 2 = total ATP….Energy yield.
| Source | ATP | Total |
|---|---|---|
| 1 acetyl CoA | x 10 ATP | = 10 ATP (Theoretically 12 ATP) |
| TOTAL | = 14 ATP |
How many ATP are produced in lauric acid?
1 mole Lauric acid (200.3 g/mol) produces 78 molecules of ATP and 1 mole palmitic acid (256.4 g/ mol) produces 106 molecules of ATP.
What is the total number of ATP generated from overall breakdown of linoleic acid?
Therefore, the total ATP yield of oxidation of linoleic acid is 117 ATP.
How many ATP does a 14 carbon fatty acid produce?
In addition, two equivalents of ATP are lost during the activation of the fatty acid. Therefore, the total ATP yield can be stated as: (0.5 * n – 1.5) * 14 + 4 – 2 = total ATP….Energy yield.
| Source | ATP | Total |
|---|---|---|
| 1 acetyl CoA | x 10 ATP | = 10 ATP (Theoretically 12 ATP) |
| TOTAL | = 14 ATP |
How much ATP does a 15 carbon fatty acid produce?
The most straightforward way to accomplish this task would be to exit as malate, and then be oxidized and decarboxylated by the malic enzyme. The ME generates NADPH, which is energetically equivalent to NADH. Therefore, total yield of ATP from the C15 fatty acid is: -2+34+15+51-1+21 = 118 ATP.
How many ATP are produced from acetyl CoA?
12 ATP molecules
Acetyl CoA produces 12 ATP molecules accounting for 3 NADH (9 ATP), 1 FADH2 (2 ATP) and 1 GTP (1 ATP) in the TCA cycle and oxidative phosphorylation in the electron transport system.
How many ATP molecules are produced per 20-carbon fatty acid oxidized?
A) About 1,200 ATP molecules are ultimately produced per 20-carbon fatty acid oxidized. B) One FADH2 and two NADH are produced for each acetyl-CoA.
How many ATPs are produced per molecule of palmitic acid?
Electron transport starting with FADH 2 yields two ATPs and with NADH yields three ATPs. Therefore, β‐oxidation yields the equivalent of 35 ATPs per molecule of palmitic acid. Each acetyl‐CoA goes into the TCA cycle, where its metabolism yields three NADHs, one FAD, and one GTP directly, for a total of 12 ATPs.
How is ATP produced from fatty acyl CoA?
Only the beta-hydroxy dehydrogenase step, which produces NADH, yields ATP. The medium and short chain fatty acyl CoA’s plus all the acetyl CoA is transported to the mitochondria for complete oxidation, using the mitochondrial beta oxidation pathway where needed.
How do you calculate the number of acetyl-CoA produced from a fatty acid?
Acetyl-CoA is a 2-carbon molecule, so to determine the number of acetyl-CoA that a fatty acid will yield, divide the total number of carbons in that fatty acid by 2 (18/2 = 9). 2. Which of the following fatty acids will produce 8 acetyl-CoA molecules after it is completely catabolized via beta oxidation?
