Energy-supplying nutrients are eventually broken down to
a. glucose and fatty acids.
b. ketone bodies and urea.
c. free radicals and oxygen.
d. carbon dioxide and water.
D
All energy-supplying nutrients are eventually catabolized to carbon dioxide and water. Glucose and fatty acids are products of digestion of carbohydrates and fat; they are not end products of metabolism. Ketone bodies are produced when fat is used for energy; they are later broken down to carbon dioxide and water. Urea is a byproduct in the breakdown of amino acids for energy. Free radicals and oxygen are not generally produced in metabolism of energy-yielding nutrients.
