21. Statement: Pernicious anemia is a serious health problem. One type of anemia from a poor diet is pernicious anemia. In this disease, there are too few red blood cells in the body and these red blood cells are too large. Pernicious anemia is now controlled by vitamin B12.1948 scientists in England and the United States discovered a red crystalline substance which they identified as vitamin B12. In 1955 they announced the chemical formula of vitamin B12. Except for protein, B12 is the largest, most complex molecule scientists know about. When a person has pernicious anemia, the doctor can inject a fraction of a gram of B12 into the muscle. The B12 restores normal blood. It makes a person comfortable because it eliminates the nervousness associated with pernicious anemia. It also helps the body use the amino acids it needs for grow. A. True B. False C.
