Some enzymes acts best in an acid medium and others in an alkaline medium. For every enzyme, there is an optimum pH where its action is maximum. Most enzymes shows activity in a pH range of about 6.0 to 7.5 i.e., neutral pH. A shift towards the alkaline or acid side rapidly decreases the enzyme activity and finally, stops it altogether
