Question

Explain the characteristics of enzyme catalysis.

Accepted Answer

Characteristics of enzyme catalysis:

A single molecule of the enzyme catalyst can transform up to a million molecules of the reactant per second. Hence, enzyme catalysts are said to be highly efficient.

These biochemical catalysts are unique to certain types of reactions, i.e. the same catalyst cannot be used in more than one reaction.

The effectiveness of a catalyst is maximum at its optimum temperature. The activity of the biochemical catalysts declines at either side of the optimum temperature.

Biochemical catalysis is dependent upon the pH of the solution. A catalyst works best at an optimum pH which ranges between $5 - 7$ pH values.

The activity of the enzymes usually increases in the presence of a coenzyme or an activator such as ${Na}^{+}, {Co}^{2 +}$ . The rate of the reaction increases due to the presence of a weak bond which exists between the enzyme and a metal ion.
