Question

Part A Explain the rationale for the production of ketone bodies during starvation. During starvation, glucose is in short supply, and the body responds by producing ketone bodies as a source of energy During starvation, the oxygen concentration in blood drops and the body responds by metabolizing nutrients to less oxidated compounds such as ketone bodies. proton concentration high enough to maintain ATP synthesis by ATP synthase. During starvation, pH gradient decreases and the body have to produce acidic ketone bodies in order to keep None of the above.

Answer 1

Ans Part A : During starvation , glucose is in short supply , and the body responds by producing ketone bodies as a source of energy.

When the body undergoes starvation and there is a lack of glucose in the blood , large amounts of ketone bodies are produced by the liver.

These ketone bodies are produced by the fatty acids which are then utilised by the gluconeogenesis process to produce energy.

Ans Part A : Stepwise oxidation of fatty acids is known as $\beta$ oxidation because the carbon $\beta$ to the thioester group (two carbons away from the thioester group) is oxidised in the process.

In beta oxidation of fatty acids , two carbons get less in each round. The bond between C-2 and C-3 carbon is broken , so basically the carbon whoch is two carbons away from the thioester group gets oxidised.
