Concept Introduction:

Enzymes level in body fluids are sometimes monitored to diagnose diseases. Any alteration in specific enzyme activity can determine the affected body organ or part.

Explanation of Solution

The level of some enzymes increases in the case of injury or stress. Based on the decreased or elevated level of certain enzymes in different tissues can determine the various diseases of particular organs. AST and ALT levels in the body fluids are monitored for diagnosis of heart attack or hepatitis...
