Here's how it works:
* Fat Catabolism: Fats are broken down into glycerol and fatty acids. Fatty acids undergo beta-oxidation, a process that generates acetyl-CoA.
* Glucose Catabolism: Glucose is broken down through glycolysis, which produces pyruvate. Pyruvate is then converted to acetyl-CoA via the pyruvate dehydrogenase complex.
Acetyl-CoA then enters the citric acid cycle (Krebs cycle), a central metabolic pathway common to both fat and glucose catabolism, to generate energy in the form of ATP.
