Enzymes are proteins that are catalysts
of chemicalreactions. From Chemistry it
is known that catalysts are nonconsumable substances that reduce the
activation energy necessary for a
chemicalreaction to occur.
Enzymes are highly specific to the
reactions they . They are of vital
importance for because most
chemical reactions of the cells and
tissues are catalyzed by .
Without enzymatic action those
reactions would not occur or would not
happen in the required speed for the
processes in which they
participate.
