Which statement is TRUE regarding the late stages of starvation?

Question

Quizplus · Accepted Answer

In the late stages of starvation, the body relies heavily on the breakdown of fatty acids for energy. As a result, high levels of acetyl-CoA are produced from lipid catabolism which can lead to the production of ketone bodies, including acetoacetate. The brain can use ketone bodies as an alternative energy source. Choice A is incorrect because the brain still primarily relies on glucose for energy, although it does decrease its glucose consumption and switch to using lactate and ketone bodies as energy sources during starvation. Choice C is incorrect because amino acids are typically conserved as much as possible during starvation to spare muscle tissue, although they can be used for gluconeogenesis in extreme cases. Choice D is incorrect because the liver primarily produces ketone bodies during starvation rather than exporting lactate from the muscle. Choice E is partially correct but the main source of carbon for gluconeogenesis during starvation is amino acids, not glycerol.
