A) Direction of the reaction is influenced by \[[{{H}^{+}}].\]
B) lonisation state of dissociating groups on the enzyme is modified.
C) lonisation state of the substrate is modified.
D) Protein is not denatured with the change in pH.
Correct Answer: A
Solution :
Most proteins and therefore enzymes are active only within a narrow pH range between 5 and 9. pH is defined as the\[-\log [{{H}^{+}}]\]i.e., the direction of the reaction is influnced by\[[{{H}^{+}}].\] It also effects the ionisation state of substrate, amino acid residues, dissociating groups on the enzyme. Extremes of pH which is not optimal for enzyme catalysed reactions to take place leads to denaturation of proteins.
