<prompt> Increased formation of ketone bodies during fasting is a result of:Decreased level of circulating glucagonDecreased formation of Acetyl CoA in the liverIncreased levels of free fatty acids in bloodInhibition of b-oxidation of fatty acids in liver  <response>: Free fatty acids bound to albumin are increased as a result of an increased activity of Hormone sensitive lipase in adipose tissue as this enzyme breaks TG into glycerol fatty acids. These fatty acids are taken up by liver. b-oxidation of these fatty acids in liver provides the acetyl CoA for ketogenesis. Hepatic ketogenesis is also stimulated by elevated levels of glucagon during fasting.
