What is the yield for the oxidation of palmitic acid?
Oxidation of of palmitic acid yields 7 NADH + 7 FADH2 + 8 acetyl-CoA in 7 cycles of mitochondrial beta oxidation. Every acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (=ATP) during Krebs cycle. Considering an average production of 3 ATP/NADH and 2 ATP/FADH2 using the respiratory chain, you have 131 ATP molecules.
How many ATP are needed for palmitic acid?
Total ATP produced are = 21 + 14 + 96 = 131 ATP But since 2 ATP is used to activate the fatty acid in the first step Therefore, 131 – 2 = 129 ATP Thus, from the oxidation of one molecule of palmitic acid, the number of ATP molecules released is 129 ATP.
How many ATP are produced in beta oxidation?
Energy yield
| Source | ATP | Total |
|---|---|---|
| 1 FADH2 | x 1.5 ATP | = 1.5 ATP (Theoretically 2 ATP) |
| 1 NADH | x 2.5 ATP | = 2.5 ATP (Theoretically 3 ATP) |
| 1 acetyl CoA | x 10 ATP | = 10 ATP (Theoretically 12 ATP) |
| TOTAL | = 14 ATP |
What does beta oxidation of fatty acids yield?
The FADH2 and NADH produced during the process of fatty acid β-oxidation are used by the electron transport chain to produce ATP.
How many ATP can a palmitic acid yield from acetyl-CoA quizlet?
105 ATPs per palmitoleic acid that is fully oxidized. The 16-carbon palmitoleic acid will go through 7 rounds of β-oxidation. This will produce 6 FADH2s, 7 NADHs, and 8 acetyl-CoAs. (If the fatty acid had been saturated, 7 FADH2s would have been produced in the β-oxidation cycles.
How much ATP is produced from the uptake and oxidation of 1 molecule of palmitic acid?
Electrons derived from the first two steps pass to O2 via the mitochondrial respiratory chain, providing the energy for ATP synthesis by oxidative phosphorylation. The net yield for the complete oxidation of a palmitic acid molecule is 129 ATP molecules.
How many cycles of beta oxidation are required for palmitic acid?
seven cycles
Palmitic acid is the most common type of fatty acid that contains sixteen carbon atoms and no carbon-carbon double bonds. In order to completely break down the fatty acid, a total of seven cycles of beta oxidation must take place. This generates a total of 8 acetyl-CoA molecules, 7 NADH molecules and 7 FADH2 molecules.
How many ATP can a palmitic acid yield from acetyl-CoA?
So the correct option is ‘129 ATP’.
How many ATP are produced from an 18 carbon fatty acid?
For an 18-Carbon saturated fatty acid (stearic acid), it will produce 9 Acety-CoA. Each Acetyl-CoA will enter the Krebs Cycle and will produce 12 ATP.
How much ATP does a 20-carbon fatty acid produce?
About 1,200 ATP molecules
A) About 1,200 ATP molecules are ultimately produced per 20-carbon fatty acid oxidized. B)
Why is ATP 36 or 38?
Explanation for Correct option: The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.
How many ATP are produced from an 18-carbon fatty acid?
How is 36 38 ATP produced?
During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria. Thus, option A is correct.
Is ATP 32 or 38?
According to some newer sources, the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose, because: ATP : NADH+H+ and ATP : FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
Why is it 36 or 38 ATP?
Where do the 38 ATP come from?
Our body produces a large amount of ATP during respiration. If glucose is the respiratory substrate, then we get the net gain of 38 ATP molecules in aerobic respiration from one glucose molecule.
Why is ATP 38 or 36?
Is it 32 or 36 ATP?
The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.
How 36 ATP is produced?
How is 36 or 38 ATP formed?
Which of the following produces 36 ATP?
Cellular respiration produces 36 total ATP per molecule of glucose across three stages. We can describe each stage’s ATP production.
How do we get 38 ATP?
How do you calculate the ATP yield of a fatty acid?
ATP yield of even-numbered fatty acids may be calculated using a formula [(7C – 6 – 1.5 D) – 2(D-2)], andadenosine triphosphate (ATP) yield for odd-numbered fatty acids can be calculated using [(7C – 19 – 1.5 D) – 2(D-2)], where C is the number of carbon atoms in fatty acids, D is the number of double bonds.
