The reaction: succinyl CoA + acetoacetate and acetoacetyl CoA + succinate occurs in all of the following Except

Thiophorase (acetoacetate - succinyl CO A, Co A transferase) is the enzyme responsible for the transfer of Co A to acetoacetate conveing it into acetoacetyl Co A which is responsible for utilization of ketone bodies. Liver cells do not have enzyme thiophorase and so they can not utilize ketone bodies.
