Quizplus · Accepted Answer

Ketones can be used by the brain as an energy source when glucose is not available. This is especially important during prolonged fasting or starvation when glucose levels in the blood are low.

Choices A, C, D, and E are incorrect because ketones are not waste products of amino acid metabolism, they are not a by-product of anaerobic metabolism, they are not converted to fatty acids and released into the blood, and they are not used to synthesize glucose by gluconeogenesis.
