Answer to Question 1

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.

Answer to Question 2

4

Rationale: Normal albumin levels are 3.55.0 gm/L. Normal prealbumin levels are 150350 mg/L. Normal transferrin levels are above 200 mg/L. Decreased cholesterol levels in older adults, who do not take cholesterol-lowering medications, are associated with an increased risk of morbidity and mortality.
