16. What is the physiological function of gluconeogenesis?
A. Gluconeogenesis is production of glucose from noncarbohydrate molecules in times when blood glucose levels are low. This ensures proper function of brain and red blood cells, which only use glucose as fuel.
B. Gluconeogenesis is production of glucose from noncarbohydrate molecules in times when blood glucose levels are high. This ensures proper function of brain and white blood cells, which only use glucose as fuel.
C. Gluconeogenesis is production of glucose from carbohydrate molecules in times when blood glucose levels are low. This ensures proper function of brain and red blood cells, which only use glucose as fuel.
D. None of the above

17. What effect does glycogen metabolism have on glucose levels?
A. Glycogen metabolism traps glucose within liver cells and increases storage of glucose in the form of glycogen. These processes decrease blood glucose levels.
B. Glycogen metabolism traps glucose within liver cells and increases storage of glucose in the form of glycogen. These processes increase blood glucose levels.
C. Glycogen metabolism releases glucose within liver cells and increases storage of glucose in the form of glycogen. These processes decrease blood glucose levels.
D. None of the above

18. Carbon monoxide binds tightly to the heme groups of hemoglobin and myoglobin. How does this affinity reflect the toxicity of carbon monoxide?
A. Since carbon monoxide binds the heme groups of hemoglobin, it is easily removed or replaced by oxygen. As a result, the effects of oxygen enhancement result in what divers call the "bends."
B. Because carbon monoxide binds the heme groups of hemoglobin, it is easily removed or replaced by oxygen. As a result, the effects of oxygen deprivation result in suffocation.
C. Because carbon monoxide binds tightly to the heme groups of hemoglobin, it is not easily removed or replaced by oxygen. As a result, the effects of oxygen deprivation result in suffocation.
D. None of the above

B. Sulfa drug binds to the enzyme, no product is formed, folic acid is made and the biosynthesis of methionine and nitrogenous bases increases.
