Question

multiple choice question
what are ketone bodies?

by-products of incomplete oxidation of fats
end products of beta oxidation
by-products of incomplete breakdown of glycogen
fatty acids released by lipolysis

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Ketone bodies are produced when fat oxidation is incomplete (e.g., during starvation or low - carb diets), so this is correct.
• Option 2: The end product of beta - oxidation is acetyl - CoA, not ketone bodies, so this is incorrect.
• Option 3: Glycogen breakdown (glycogenolysis) produces glucose, not ketone bodies, so this is incorrect.
• Option 4: Lipolysis releases fatty acids, not ketone bodies, so this is incorrect.

Answer:

A. By - products of incomplete oxidation of fats
