Please describe how ketone bodies are formed during starvation

Answer #1

Formation of ketone bodies during starvation:

  • During starvation, carbohydrate intake will be low and the ketone bodies are released by the liver into blood during starvation.
  • Acetyl CoA generated by the oxidation of fatty acids in the liver, helps in synthesizing ketone bodies. During that oxidation, some of the important fatty acids mobilized from the adipose tissue, is are to the ketone bodies for the metabolism of brain.
  • These ketone bodies are mainly produced in the mitochondria of liver cells.
  • So, the metabolization of ketone bodies helped diminished the use of glucose during starvation and the brain can obtain its energy requirements from the ketone bodies, which are formed from fatty acids.

In this way, ketone bodies are formed during starvation.

Which ONE of the following statements about the processes that occur during starvation is FALSE? Choose the best answer During starvation, the liver exhausts its glycogen stores within the first day. During starvation, the liver increases its capacity for gluconeogenesis. After depletion of liver glycogen, fatty acids become the primary source of gluconeogenic precursors used for glucose synthesis. Increased reliance on ketone bodies for fuel reduces the breakdown of proteins and spares the remaining glucose for use by the brain....

1. The ketone bodies made by ketogenesis are ketones (functional group), true or false? *This is a note from me, the student: the products of ketogenesis, ketone bodies are: 1) 3-Hydroxybutyrate (does not have a ketone functional group) and is a byproduct of 2) acetoacetate (has a ketone functional group). So, based on this, is the question true or false? This a biochem assignment. Thank you in advance
