How much the number of ATP produces from 12-Carbon Fatty acid?

Answer 1

sorry its not 15 ATP but 80 ATP

12 carbon fatty acid is called Lauric acid
it undergoes
1. 5betaoxidation cycles:it produces
5 FADH2(oxidised by electron transoport chain,each FADH2 gives 2 ATP molecules as 5 Beta oxidation cycles it is 5*2=10 ATP

2. From 6acetly CoA(acetly CoA is a 2carbon compound As lauric acid has 12 carbon it can produce 6 Acetyl CoA)
Oxidised by citric acid cycle each acetyl CoA provides 12 ATP molecules therefore 72(6*12) ATP are produced

Total eneergy from one molecule of lauric acid is 82 ATP(10+72)
But 2 ATP molecules of energy is utilised for the activation(i;e., formation of lauricoyl CoA) so net yield of one molecule of lauric acid is 80ATP(82-2) .

Beta Oxidation:Oxidation of fatty acid occurs at the beta carbon,resulting in the formation of a molecule of acetate(2 C) from the terminal two carbons and leaving the residue of fatty acid containing 2carbon less than the original(in this case in the first beta oxidation cycle C10 fromed from C12 leaving acetae i.e 2 C,which again forms acetly CoA).This process repeats itself untill the fatty acid with even number carbon is completely converted to acetate(2C) molecule.(so in lauric acid 5 betaoxidation cycles are possible in C16 =7beta oxidation cycles and in C18=8cycles ..........)

Answer 2

I calculated 97. The answer you picked skipped the calculation of NADH. 97 - 1 for fatty acid activation is 96. So 96 ATP for a a 12 - carbon fatty acid.

Answer 3

palmitate is a 16 carbon fatty acid the oxidation of a molecule of palmitoyl CoA to CO2 and H2O produces 8 acetyl CoA, 7 NADH, and 7 FADH2, from which 131 ATP may be generated (electron shipping chain); in spite of the undeniable fact that, activation of the fatty acid calls for 2 ATP. as a outcome, the web yield from palmitate is 129 ATP the no of acetyl CoA produced is not any of C/2, the no of NADH and FADH2 is not any of C - a million because the finest step in undemanding words produces a million NADH and FADH2 and 2 acetyl CoA

Answer 4

15 ATP

3 ATP for every AcetylCoA ( 2 carbons) that can be peeled apart

In a 12 carbon Fatty acid there are 6 pairs of carbons, and 5 bonds that can be used for ATP production
