Under conditions of starvation, acetyl-CoA, instead of being degraded in the citric acid cycle, is converted to acetone and 3-hydroxybutyrate, compounds called ketone bodies that the brain can use as a temporary fuel. Show how the ketone bodies are formed.

Which statements describe electron transport chain events? Two electrons pass between cytochromes through a series of redox reactions. Citrate metabolism results in the formation of one FADH2 and three NADH. NADH releases two hydrogen ions and donates two electrons to coenzyme Q. ATP synthase uses the energy from the redox reactions to generate ATP.
Acyl-CoA synthase is the enzyme that activates a fatty acid by converting it to a fatty acyl-CoA in a series of two reactions. In the first reaction, the fatty acid reacts with ATP and one of the products formed is ADP. The other product reacts in a second reaction with CoASH to form the fatty acyl-CoA. Propose a mechanism for each of the reactions.
Energy from the breakdown of citrate (formed from acetyl groups) is captured by what compound in steps 3, 4, and 8 of the citric acid cycle?
