How do Enzymes work?
... All chemical reactions in all living organisms require enzymes to function; actually, no existing reaction can take place without an enzyme. They have the principal function of being biological catalysts (speed up reactions), but they also work as being synthesis enzymes (building reactions) and dig ...
