Question

How many ATP can be produced by the complete oxidation of each propionyl-CoA product of fatty acid oxidation? Compare this to the ATP yield for each acetyl-CoA

Answer 1

The complete oxidation of each propionyl-CoA product of fatty acid oxidation produces 6ATP .

Step-by-step explanation:

When an odd chain is contained in the oxidation of fatty acids ; the last round of the Beta-oxidation of odd chain fatty acids, one Acetyl CoA and Propionyl CoA are produced, then Propionyl CoA gets converted in to Succinyl CoA.

This means that carboxylation reaction must be undergone by Propionyl CoA, and this requires Biotin and Vitamin B12. Afterwards, these reactions produce Succinyl CoA.

Succinyl CoA has an anapleoretic fate and its molecule goes into the Krebs Cycle (citric acid cycle) which generate Oxalacetate.

This means it produces 1 GTP+1FADH2+1NADH = (1+2+3) = 6ATP ; and each Acetyl CoA produces 12 ATP during oxidization in the citric acid cycle.

Answer 2

6ATP

Step-by-step explanation:

one Propionyl CoA and one Acetyl CoA are produced, then Propionyl CoA converts in to Succinyl CoA.

means it produces 1 GTP+1FADH2+1NADH=(1+2+3)=6ATP

And each Acetyl CoA yields 12 ATP when getting oxidized in the citric acid cycle.
