Beta-oxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport chain.
Correct option is : • It enters the Kreb's cycle.
Add Answer to:
What is the fate of the acetyl CoA produced during beta oxidation? O It is sent...

What is the fate of pyruvic acid in an organism that uses aerobic respiration? O A. It is reduced to lactic acid. OB. It is converted into acetyl CoA before the Krebs cycle. OC. It is oxidized in the electron transport chain. OD. It is catabolized in glycolysis. Reset Selection
What is the difference, in number of ATPs produced, between the oxidation of acetyl-CoA and propionyl-CoA?...
What is the difference, in number of ATPs produced, between the oxidation of acetyl-CoA and propionyl-CoA? Assume for this question that all molecules enter citrate cycle and produce CAC products. Hint: Proprionyl CoA is converted to succinyl CoA. For this question assume that succinyl CoA enters CAC and continues all the way through (does not leave the cycle as malate).
