Metabolic processes result in growth, produce energy, eliminate wastes, and control other body functions which distribute nutrients in the blood after food is digested.
Metabolism maintains homeostasis , or a steady state, in the body.

Each disease is a block in changing one chemical to another. The impact on the person with one of these defects varies widely. There may be no symptoms with some defects.
