What:

"The living organism is like a well-maintained chemical factory: a number of organic compounds are incessantly produced and degraded, while various inorganic materials-non-carbon compounds, metals, and minerals-are consumed, to keep the system alive. Almost all chemical reactions in this factory are catalyzed by protein molecules called enzymes. As catalysts, enzymes speed up enormously (10-billion-fold) the rate of specific biochemical reactions. "
