Function and structure. Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.
Enzymes work most efficiently under a certain pH concentration, i.e. optimum pH. When pH alters, the bonds on the active sites of the. enzymes are affected which will change the shape of the active sites. and the formation of enzyme-substrate complexes will be slowed down.
