Explanation Justification/Explanation for the correct answer: Option (d) is given that Kyle’s body cells are unable to utilize carbohydrate as fuel and so, the liver converts fats into ketone bodies. The production of ketone bodies or ketogenesis occurs mainly in the cells of the liver (hepatocytes) when carbohydrate as a source of energy is absent or when the cells fail to take up carbohydrates efficiently from the blood. Thus, fats are metabolized by the hepatocytes. The fatty acids formed by lipolysis (fat breakdown) are converted into acetyl coenzyme A (acetyl CoA) through beta-oxidation. When glucose is absent, these molecules of acetyl CoA are unable to enter the citric acid cycle and are converted into ketone bodies by hepatocytesHence, option (d) is correct. Explanation for the incorrect answers: Option (a) is given that the main ketone source is diet, thus Kyle must be eating or drinking it...
