Answer to Question 1

ANS: B
Nonhydroxide bases. Ammonia and carbonates are good examples of nonhydroxide bases. Pro-teins, with their amino groups, also can serve as nonhydroxide bases.

Answer to Question 2

ANS: C
Protein bases. Proteins are composed of amino acids bound together by peptide links. Physiolog-ic reactions in the body occur in a mildly alkaline environment. This allows proteins to act as H+ receptors, or bases. Cellular and blood proteins acting as bases are transcribed as prot. The imid-azole group of the amino acid histidine is an example of an H+ acceptor on a protein molecule (Figure 12-4). The ability of proteins to accept hydrogen ions limits H+ activity in solution, which is called buffering. The ability of hemoglobin to accept (i.e., buffer) H+ ions depends on its oxy-genation state. Deoxygenated (reduced) hemoglobin is a stronger base (i.e., a better H+ acceptor) than oxygenated hemoglobin.

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Glaucoma is a leading cause of blindness. As of yet, there is no cure. Everyone is at risk, and there may be no warning signs. It is six to eight times more common in African Americans than in whites. The best and most effective way to detect glaucoma is to receive a dilated eye examination.

Patients who have undergone chemotherapy for the treatment of cancer often complain of a lack of mental focus; memory loss; and a general diminution in abilities such as multitasking, attention span, and general mental agility.

The term bacteria was devised in the 19th century by German biologist Ferdinand Cohn. He based it on the Greek word "bakterion" meaning a small rod or staff. Cohn is considered to be the father of modern bacteriology.

People with alcoholism are at a much greater risk of malnutrition than are other people and usually exhibit low levels of most vitamins (especially folic acid). This is because alcohol often takes the place of 50% of their daily intake of calories, with little nutritional value contained in it.
