Verified step by step guidance

Beta oxidation is a metabolic process that occurs in the mitochondria, where fatty acids are broken down into acetyl-CoA units.

Fatty acids are first activated in the cytoplasm by being converted into fatty acyl-CoA, a process that requires ATP.

The activated fatty acyl-CoA is then transported into the mitochondria via the carnitine shuttle, which involves the conversion to acyl-carnitine.

Once inside the mitochondria, the fatty acyl-CoA undergoes a series of reactions: dehydrogenation, hydration, another dehydrogenation, and thiolysis, resulting in the production of acetyl-CoA.

The acetyl-CoA produced can enter the citric acid cycle to be further oxidized for energy production, or it can be used for other biosynthetic pathways.
