The effects of pH on enzymes depends on a combination of factors: 

(a) Most enzymes are active within only a narrow pH range, typically 5 to 9. 

(b) the ionization states of the amino acid residues involved in the catalytic activity of the enzyme

(c) the variation of protein structure (usually significant only at extremes of pH).
