Final answer:
Liver mitochondria have the capacity to divert excess acetyl CoA derived from fatty acid or pyruvate oxidation into ketone bodies.
Step-by-step explanation:
Liver mitochondria have the capacity to divert any excess acetyl CoA derived from fatty acid or pyruvate oxidation into Ketone bodies. When fatty acids are oxidized, excess acetyl CoA can accumulate in the liver. This excess acetyl CoA is then converted into ketone bodies through a process known as ketogenesis.
