Question

The body uses ketone bodies as fuel “during times of extreme starvation” and that ketosis “is an important survival mechanism that maintains high rates of fatty acid oxidation when carbohydrate stores are depleted” but that “it can lead to pathologic conditions.” Summarize what ketosis is metabolically, including figure 16.15 from the text in your summary.

Ketone bodies produced in the liver are exported into the blood.
