Question

multiple choice question
ketones are produced by the incomplete oxidation of which of the following?

• glucose
• glycogen
• proteins
• fats

Explanation:

Ketones are produced when the body breaks down fats for energy instead of glucose (in cases like fasting or low carbohydrate intake), due to incomplete oxidation of fatty acids. Glucose oxidation produces ATP and carbon dioxide/water, glycogen is a glucose storage form, and proteins are not the primary source for ketone production. So fats are the correct source.

Answer:

D. Fats
