In starvation, the body makes a major adaptation to conserve its protein stores

Question

Quizplus · Accepted Answer

During starvation, the body enters a state of ketosis where it utilizes ketone bodies derived from fat stores as an alternative energy source, particularly for the brain and nervous system, sparing protein breakdown for energy.

Answer: D
 During starvation, the body partially relies on fatty acids as an energy source, which results in incomplete metabolism and the production of ketone bodies. However, this is not the major adaptation for protein conservation.

Option A is incorrect because the body cannot synthesise all essential amino acids and requires them to be obtained from the diet.

Option B is incorrect because neutralising metabolic by-products such as urea and creatinine is a regular function of the liver and kidneys, even in non-starvation conditions.
