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).

Which of the above is correct
