Which organ does not utilise ketone bodies 
Select and explain. 
A. Liver, B. Brain, C. Skeletal muscles, D. Cardiac muscles
A: Liver
Answer: A: Liver 
Explanation: Liver

Ketone bodies are synthesized by the liver and are utilized by extrahepatic tissues like heart, muscles, renal cortex and brain (in starvation).
Liver cannot utilize ketone bodies because it lacks enzyme succinyl-CoA-acetoacetate CoA transferase, which is required for the activation of ketone bodies.
