28-2

ANS: 3
When fats are converted to ketones for use as alternative fuel, as in diabetic ketoacidosis when glucose cannot by used by the cells, the acidity of the blood rises, leading to the acidosis. Glycogen is converted to glucose to meet energy needs. Insulin, a pancreatic hormone, promotes the movement of glucose into cells for use. Proteins would not be used for fuel as long as fats were available.

ANS: 2
A positive nitrogen balance typically exists during pregnancy when new tissues are being formed. Patients with burns, malnutrition, and serious illness commonly experience negative nitrogen balance because tissues are lost.
