Which of the following is true about ketone bodies:
Ketone Body Synthesis Catabolic pathway Occurs in mitochondria Activated by glucagon Occur in liver 1st ketone body - acetoacetate Most common ketone body - Beta hydroxy butyrate Found in blood and urine Ketone Body Utilization Catabolic pathway Occurs in mitochondria Activated by glucagon Occur in brain, hea and muscles Thiophorase is absent in liver so ketone bodies cannot be utilized by liver.
Acetoacetate is most common ketone body present in blood
Beta hydroxybutyrate is the first ketone body to be synthesized
Thiophorase is absent in liver
Muscle can not utilize ketone bodies
Beta oxidation of fatty acids
