Question:
A prisoner goes on a hunger strike to protest the conditions of his detainment. After several days, his blood glucose level is significantly reduced. In order to keep a constant supply of energy to his brain and muscle, which of the following molecules is his liver releasing?
Correct Answer: A. Beta-hydroxybutyrate
The liver’s role during starvation is to release both glucose (via gluconeogenesis) and ketone bodies into the blood. Most available glucose is usually reserved for the brain during starvation. Adipose tissue provides fatty acids both for muscle and liver. Liver converts about half of the fatty acids it takes up into ketone bodies (acetoacetate and b-hydroxybutyrate), which it releases into the blood.
