Where does the conversion of pyruvate to acetyl CoA occur?

NettetIn normal condition, acetyl-CoA is mainly channeled into the Krebs cycle for energy production. In overnutrition state, acetyl-CoA can be used to store excess energy by forming fatty acids. Acetyl-CoA is also the source for cholesterol synthesis. In starved state, acetyl-CoA is converted into ketone bodies.
