Serum Isoenzyme Measurements Are Useful in Diagnosis Because

Serum isoenzyme measurements are useful in diagnosis because

A) the composition of the serum changes specifically with specific diseases.
B) different tissues may contain different isoenzymes and any damage to a particular tissue releases only its characteristic isoenzymes into serum.
C) different tissues may have the same isoenzyme composition and a given disease specifically releases only certain disease-specific isoenzymes into serum.
D) the disease process causes the damaged tissue to synthesize and release specific isoenzymes as a defense mechanism specific for a given disease.
E) isoenzyme measurements are expensive and are a good way for hospitals to increase their profits.
