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

Pharmacology
How do sulfa drugs selectively kill bacteria while causing no harm to humans?
A. Folic acid is a vitamin required for the synthesis of a coenzyme needed to make the amino acid methionine and the purine and pyrimidine nitrogenious bases for DNA and RNA and folic acid is produced by humans.
B. Sulfa drug binds to the enzyme, no product is formed, folic acid is made and the biosynthesis of methionine and nitrogenous bases increases.
C. Humans are not harmed because they do not synthesize their own folic acid. It is obtained in the diet.
D. None of the above
Pharmacology
What occurs when glycogen metabolism is stimulated by insulin?
A. Insulin stimulates glycogen synthase, the first enzyme in glycogen synthesis.
B. Insulin stimulates glycogen synthase, the first enzyme in glycogen synthesis. It also stimulates removal of glucose from the bloodstream into cells and phosphorylation of glucose by the enzyme glucokinase.
C. Insulin stimulates glycogen synthase, the first enzyme in glycogen synthesis. It also stimulates uptake of glucose from the bloodstream into cells and phosphorylation of glucose by the enzyme glucokinase.
D. All of the above
