Chemistry - Enzymes
Often referred to as biological catalysts, enzymes are proteins with a
specific region on the structure, called the active site,  with which
reacting molecules must make contact. Access to the active site on a
particular enzyme is available only to particular molecules. However, this
specificity and enzyme function is destroyed if denaturation occurs, since
the exact structure is the key to the effective functioning of all proteins
in the body. Enzymes also function in a very narrow temperature range.
Enzymes are amazing in their There are thousands of reactions occurring
throughout your body at any time. But a particular enzyme will only control
one reaction. The active site will only accept specific molecules, which
have a shape complementary to that of the active site. Enzymes produce
faster reaction rates than most industrial catalysts  and they operate
under much less severe conditions than industrial catalysts.
